GASEOUS AND LIQUID FLUORINE

Rolf Prydz and Gerald C. Straty

ABSTRACT

An apparatus has been constructed and used successfully to measure vapor pressure and PVT data of fluorine from

the triple point to 300 K at pressures to about 24 MN/m2

. Material

problems caused by the toxic and corrosive nature of fluorine were

solved. A network of isotherm and isochore polynomials and a truncated virial equation were used to represent all PVT data.

These equations represent the data with an average standard deviation of about 0.0Z percent in density, the corresponding accuracy

being estimated at . 1 percent. Equations for the saturated liquid

and vapor densities, the vapor pressure curve, the melting line,

and the ideal gas properties are also presented. Comparisons

are given to published values of the second virial coefficients,

vapor pressures, and saturation densities. Additional comparisons

are also made to measured specific heats and latent heats of vaporization. New values are reported for the triple point and critical

point parameters together with the temperature and saturation densities at the normal boiling point. Finally, extensive tables of

thermodynamic properties of fluorine are given which include pressure, temperature, density, isotherm and isochore derivatives,

internal energy, enthalpy, entropy, specific heats at constant pressure and volume and velocity of sound.

Key Words: Density; enthalpy; entropy; fixed points (PVT); fluorine;

I. INTRODUCTION

Current increased technical and scientific interest in fluorine

arises from the fact that this cryogenic fluid is being considered as

a propellant oxidizer in rocket propulsion systems. The reason is

that liquid fluorine is one of the most energetic oxidizers known

and its use with hydrogen as a fuel results in the most favorable

specific impulse of any stable oxidizer -fuel combination. Since the

product of the reaction is hydrofluoric acid, the use of this combination is limited to upper stages of the rocket.

The highly toxic and reactive properties of fluorine have,

however, discouraged research in determining its physical properties which are required for engineering calculations and systems

development. For example, a few parts per million of fluorine in

the air is fatal to humans. Also, hydrofluoric acid resulting from

fluorine reactions in poorly cleaned systems may actually react

with any metal used as the containment for this reactive fluid. As

a result, physical property data on fluorine tend to be quite inaccurate, extremely scarce, and in many cases, nonexistent.

The primary objective of this research program was, therefore, to determine the complete PVT relationship for gaseous and

liquid fluorine to be used for calculating thermal functions. These

PVT measurements are also required for future experimental

fluorine measurements in this laboratory of thermodynamic and
transport properties such as specific heats (which have been

completed at the time this is being written), velocity of sound,

dielectric constant, viscosity, and thermal conductivity. Valuable

knowledge concerning intermolecular forces may be gained from

the PVT measurements; for instance, information about the intermolecular potential can be obtained from the temperature dependence of the second virial coefficient. Further, correlation of

these PVT data to calculate thermodynamic properties also requires vapor pressure data from the triple point to the critical

point presented in the form of a vapor pressure equation. Finally,

to make technical design of fluorine systems possible, extensive

tables of thermodynamic properties of the saturated and s ingle

phase regions are essential.

Although reports on some specific phases of this research

have been published, it is the purpose of this note to present,

under a single cover, the complete and detailed results of the PVT

experimental and calculational program. Extensive tables of PVT prop,

erties and derived thermodynamic functions are given. The experimental method and apparatus are discussed and calculational procedures for data correlations and thermodynamic properties computations are presented.
II. EXPERIMENTAL PVT METHODS

Several different methods for accurate PYT data measurements are used in various laboratories throughout the world. While

the procedures for measuring ores sure and temperature are standard and vary little from laboratory to laboratory, drastically different methods are employed in obtaining the corresponding specific volume or density, A thorough review of these PVT measurement methods is given by Sengers Ll].

In general there are four different procedures that are used

to obtain the specific volurne, namely the Piezometer Method, the

V," eight Method, the Isochore Method, and the Gas Expansion

Method. The latter method, -which is the mcst widely used one,

will be discussed in greater detail than the other methods since it

is the approach used for this work.

A. The T-iezcuueter I iethtd .

This procedure uses a piezometer of known volume and a

calibrated stem as shown in Figure 1. a. It is filled with the fluid

under study to a pressure of 1 atmosphere and controlled at a

temperature where the isotherms of the fluid are known. Thus the

total amount of the fluid (the normal volume) in the piezometer is

available. A capillary connects the stem to a pipet of known

volume. Hence, measurements of P-V ooints at different oioet

isotherms are possible by gradually displacing the fluid from the

piezometer to the pipet or vice versa. Thus the specific volume

of the fluid in the pipet is easily computed from the known total

sample amount and the quantity remaining in the piezometer stem

which may be calculated from the known fluid properties at that

temperature.

The advantage of this method is that only one normal volume

determination is needed for a large range of pressures and temperatures. However, accurate volume determinations at high pressures are experimentally difficult since the ratio between volumes

occupied by the fluid at 1 atmosphere and at high pressures becomes very large at low pipet temperatures. Another disadvantage

of this method, which made it impractical for this work is that

known P-V properties of the fluid are required at the piezometer

temperature. No such data were available for fluorine.

B. The Weight Method . A pipet of known internal volume is suspended from a balance

as shown in Figure l.b. It is filled with a sample of fluid to a

selected pressure and temperature and the increase in weight is

recorded. These conditions provide the necessary information

for one PVT data point.

An obvious advantage of this method is that no normal volume

determination is required. However, the disadvantage associated

with obtaining an accurate value for the sample weight far outweighs
this advantage. The difficulty of the sample weight determination

is partly due to the fact that a compromise must be made between

the freedom of motion of the pipet and its thermal contact with the

surroundings. The main factor destroying the accuracy of this

measurement is, however, the weight of sample being only a

small fraction of the weight of the pipet.

C. The Isochore Method,

Figure l.c is a schematic of the apparatus used in this

method. A pipet of unknown volume is filled with a sample of the

fluid and the pressure is measured at a temperature where

the P-V relationship of the fluid is known. This permits evaluation of the specific volume of the fluid at these conditions. P-T

data for that specific isochore and for other isochores may then be

obtained in the same manner. Since the pressures are usually

measured at the same temperatures for each isochore the resulting PVT data are rearranged in isotherms without difficulty.

The fact that no volume calibration or measurement of normal

volumes are needed, makes this method quite attractive for obtaining PVT data. However, the requirement of existing accurate

high-pressure data eliminated this procedure for application to

fluorine since no such data were available.

D„ The Gas Expansion Method .

The gas expansion method is generally used in most laboratories to obtain accurate PVT data, especially where large amounts
of data are required. The time consuming calibrations of the

pipet volume, the volumes of the vessels, and other noxious

volumes are over -shadowed by the fact that only one normal

volume determination is needed for every P-T relationship (isochore) measured. Some low-density isochores for fluorine resulted in as many as 40 PVT data points.

With reference to Figure 1- d the pipet of calibrated (calibration procedure is discussed in Chapter IV) volume in the cryostat

is filled with the fluid to be studied at approximately the desired

density. Then P-T points are measured at conditions of nearly

constant density. When either the desired maximum temperature

or pressure is attained in the pipet, the fluid is released into

expansion vessels of calibrated volumes, combined in such a

manner as to give a final pressure close to 1 atmosphere. This

pressure is then generally measured with the aid of a manometer;

in the case of fluorine a quartz bourdon tube gage was used due to

the extreme reactivity of fluorine gas with manometer fluids even

at low pressures. The vessel temperature is precisely controlled by a bath at a temperature, close to the room conditions.

Thus, the total amount of sample in the pipet, the cryostat capillary, and the null pressure detector is determined applying the

gas law to the state of the sample fluid in the expansion vessels.

The compressibility factor, Z = PV/RT, of the gas under these

conditions may be obtained from a Burnett [z] expansion experiment
as discussed in Chapter VII. To obtain the actual amount of fluid

in the pipet alone, the portion of sample in the cryostat and the

null pressure detector, which is dependent upon temperature, is

subtracted from the total amount of sample. The experimental

density at each P-T point is obtained by dividing the amount of

sample in the pipet by its calibrated volume corrected for temper

ature and pressure effects as discussed in Chapter IV. Since the

density decreases slightly with increasing temperatures along a P-T relationship, the experimental run is usually denoted as a

pseudo-isochore.

This expansion method was determined to be the most practical one for fluorine for the following reasons:

1) large amounts of data could be obtained with relative

ease and great accuracy;

2) no initial accurate PVT data of fluorine were required,

and

3) an all metal apparatus, with the exception of the lowpressure pyrex glass expansion flasks, could be utilized

minimizing the hazards of data collection. The apparatus

used is discussed in the next chapter.
III. EXPERIMENTAL APPARATUS

A. Introductory Remarks.

In the early stages of fluorine technology development, a

number of failures occurred that were characterized by the

chemical ignition between the fluorine and its containment. The

ignition zone was usually consumed in the reaction and the reason

for failure was difficult to determine. It was believed, however,

that either organic contamination or incompatibility of the materials was the cause. Later tests confirmed that most common

metals are compatible for use in a fluorine environment, provided that the system is maintained completely free of contamination. Consequently, the high pressure section (up to ZO MN/m2

;

1 MN/m2 = 9. 86923 atm) of the fluorine system in this study was

constructed of stainless steel, copper, and brass with packless

metal valves. In the low pressure section (atmospheric and

below) polytetrafluoroethylene was used in a few places and the

gasometry flasks were constructed of pyrex glass. The cleaning

and passivating procedure of this equipment is described in detail

in Chapter VI.

The experimental apparatus, not including the electronics

and instrumentation is shown schematically in Figure 2 and is

similar to that used by Goodwin [3] for hydrogen and by Weber L4J

for oxygen. However, several modifications were incorporated
10
11

to minimize the problems that arise due to the toxic and reactive

nature of fluorine [5], The fluorine supply system, the cryostat,

and the vacuum pumps are separated from the instrument room by

an explosion-proof wall. Since fluorine pressure in the gasometer

glass flasks generally is atmospheric or below, the gasometer is

conveniently located in the instrument room.

All system components handling fluorine are enclosed in

aluminum cabinets and vented by a separate ventilation system.

Thus, in case a leak should develop, fluorine would rarely be

released into the laboratories. Also, the enclosures are of sufficient strength to give reasonable blast protection from direct

effects of any explosive reaction.

B. Cryostat and Pipet . A cross-section of the metal cryostat is shown in Figure 3.

The 2 6 -cm3 pipet sample holder, also called the PVT cell, is

suspended in the lower portion of the cryostat by a thin-walled

stainless steel reflux tube as pictured in Figure 4. Gaseous or

liquid nitrogen or gaseous helium in this tube cools the pipet.

This pipet is a 1. 59 cm diameter cavity bored into a solid 5 cm

diameter copper cylinder 21. 6 cm long as described by

Goodwin [3J. A plug was silver soldered into the lower end of

the pipet sample holder while the cavity was filled with helium to

avoid oxidation of the copper. Helical grooves were machined on

the outside of the cylinder to carry a 32 -gage, 500 ohm constantan

wire heater, which permits a maximum heating rate of about 1 to

2 K per minute depending on the operating temperature. The

platinum resistance thermometer was tinned and secured in the

thermometer well of the pipet with Rose's alloy. A guard ring is

supported about 5 cm above the pipet by the reflux tube. This

ring is automatically controlled to match the pipet temperature

and thermally tempers the electrical leads which are wound around

this copper cylinder before they are connected to the pipet. The

temperature control of the guard ring is obtained by a gold -cobalt

versus copper differential thermocouple between the pipet and the

guard ring. A power supply provides the current for a 36-gage,

100 ohm constantan wire heater after receiving the amplified

thermocouple signal. Tempering of the electrical leads entering

the cryostat at room temperature is accomplished by thermally

anchoring them to a cold ring suspended from the liquid refrigerant tank. Good thermal contact on the ring is insured because

all wires were assembled as one unit in a parallel plane and varnished together before they were mounted.

The pipet is surrounded by an evacuable copper jacket soldered to the refrigerant tank with Rose's alloy. This jacket, which

also serves as the cold wall, and the refrigerant tank are then, in

turn, enclosed in another vacuum jacketed dewar. Finally, the

cryostat is immersed in an open liquid nitrogen dewar having a
15

three -step electronic liquid level indicator. Arrangement of forepump, diffusion pump and vacuum valving for the cryostat is

shown in Figure 5.

The liquid nitrogen is supplied to the inner refrigerant tank

through a permanent transfer line. A suitable valving and safetysystem permits pumping on the nitrogen to attain the triple point

temperature of nitrogen and below.

Valves 9 and 10 (shown in Figure 2) on top of the cryostat

may be operated from the instrument room through appropriate

gearing and extended stems. These valves were designed by

Straty [6\ for the purpose of handling corrosive fluorine at more

than 20 MN/m2

. He modified a commercially available valve,

valve A as shown in Figure 6, with bellows (valve B) such that the

primary non-metallic packing was avoided.

A 0. 033 cm inside diameter stainless steel capillary connects valves 9 and 10 to the pipet. The fluorine -nitrogen separator (NPD), a commercial diaphragm differential pressure cell, is

connected between the pressure measuring system (Chapter III. E)

and the capillary at the top of the cryostat.

C. The Gasometer .

The gasometer consists of four calibrated volumes. These

are spherical glass flasks of approximately 1 to 2 1 liters submerged in a precision thermostated water bath conveniently con-

trolled at 295. 00 ± 0. 01 K, the approximate instrument room temperature. A higher bath temperature was not chosen since this

would have resulted in a greater bath temperature fluctuation and

excessive loss of water by evaporation into the ventilation system.

The temperature controller was adjusted according to a precision

thermometer, readable to ± 0.001°C, and which was previously

calibrated against the pipet platinum resistance thermometer.

A 0. 35 MN/m2 fuzed quartz bourdon tube type gage with

pressure readings reproducible to 7 N/m2

, was connected to the

valve manifold. When the fluid in the pipet, cryostat capillary,

and the diaphragm cell is released into the gasometer, a standard

volume is chosen such that the final pressure in the calibrated

volumes is close to 1 atmosphere. Lower pressures will cause

a larger relative error in the pressure reading, whereas higher

pressures may break the 6- or 21 -liter bulb. The quartz bourdon

tube type of gage was frequently calibrated against a high-precision

air dead-weight gage (accuracy of ± 0. 015 percent of reading) to

eliminate any error that might arise due to possible changes in the

elastic properties of the quartz tube from exposure to fluorine.

Later when an apparent weakening of the tube was observed, it was

used as a null indicator and the pressure measured with the deadweight gage. To compromise between low noxious volumes and

adequate pumping speeds copper tubing of 0. 32 cm inside diameter
19

was used to connect the flasks to the manifold. The brass manifold valves (valves 11, 12, 13 and 14 on Figure 2) were of the

bellow seal type and were kept fully open or closed depending on

whether the specific calibrated glass flask was to be filled or not.

D. The Fluorine Supply System .

Commercial grade fluorine gas was obtained in one half

pound cylinders pressurized to approximately 2.4 MN/m2

. This

gas was further distilled by Argonne National Laboratory to 99. 99

percent purity, with the remaining impurities being mostly oxygen,

nitrogen, and hydrogen fluoride as determined from residual gas

analysis after reaction of the fluorine with mercury.

A double valving manifold system of brass needle type

valves permits fine control of the fluorine flowrate to the hydrogen

fluoride absorber (Figure 2). This HF trap consists of a section

of standard 5 cm Cu-Ni pipe equipped with caps, thermowell, and

electric heating wires. The absorber is packed with sodium bifluoride (NaHF2 ) pellets and was activated prior to installation by

heating to about 300 °C while simultaneously purging with dry

nitrogen. This activation procedure drove off the hydrogen

fluoride leaving a porous absorbent form of sodium fluoride (NaF).

The trap may be reactivated in the same manner after 8 to 1 1 kg

of fluorine have been processed. A fluorine compatible bourdon

pressure gage indicates the pressure in the absorber at any time.
20

The fluorine storage and recovery cylinder is a 3 -liter

heavy -walled AISI 304 stainless steel cylinder having a maximum

operating pressure of about 12 MN/m2

, which is five times the

normal cylinder pressure. Figure 7 shows the fluorine supply

and the cryostat cabinets.

Valves 4, 5, and 8 (Figure 2) are all Cu-Ni forged needle

valves, whereas valves 6 and 7 are the same modified type as

valves 9 and 10, described earlier and shown in Figure 6. Valves

6 and 7, however, are separate, single valves. The thermal

booster is used to monitor the PVT cell filling pressure and to recover the fluorine after the gasometer measurements. The construction features of this unit were quite similar to those of the

pipet. A cavity of 2. 30 cm diameter was bored into a solid AISI

type 304 stainless steel cylinder 4 cm in diameter. A plug was

arc welded into the end of the booster while the filling line, a

0. 32 cm outside diameter copper tube, was silver soldered into

the top. A liquid nitrogen dewar may be raised and lowered

around the cylinder through a hoist arrangement operated from the

instrument room. Provisions were also available for lowering the

temperature of the refrigerant bath to its triple point and below

by pumping on the nitrogen dewar to recover more of the fluorine.

E. Measurement of Pressure .

1. Apparatus and Method

The commercial oil operated, dual range, precision deadweight gage pressure measuring system, shown in Figures 8 and

9, is the same as the one used by Weber L4J and is a modification

of the system used by Goodwin [3]. The system includes two null

pressure detectors, often referred to as commercial diaphragm

cells, with nitrogen serving as the intermediate fluid. The first

null pressure detector separates the oil in the dead-weight gage

from the nitrogen gas system, whereas the second separates the

nitrogen from the fluorine sample. Hence, in the event of a failure of the diaphragm in the null pressure detector, high pressure

fluorine gas will not come in contact with the oil to cause a

hazardous and explosive condition. Even though the diaphragms

are constructed of 0.005 cm thick steel sheets, they can withstand

overpressures of up to 100 MN/m2 and exhibit negligible temporary

hysteresis.

The second null pressure detector shown in Figure 8 is

placed on top of the cryostat to minimize noxious volumes. The

rest of the pressure measuring system is located in the instrument room. The oil and the nitrogen pressures are adjusted by

hand-operated screw-type pumps. With practice the two-diaphragm system may be operated with as much sensitivity as the

one -diaphragm system of Reference L 3 J _

The dual pressure ranges of the oil dead-weight gage are

obtained by means of interchangeable piston-cylinder assemblies,

the diameters of which are measured to ± 1.3 x 10~ 5 cm using a

light -wave micrometer. The weights are equivalent to class "P"

standard masses. Each weight is individually adjusted to match

the effective area of the piston-cylinder assembly and is calibrated

against Class "S" standard masses as certified by the National

Bureau of Standards L7j. This corresponds to a 0. 05 percent

tolerance on the 1 psi weight decreasing to 0. 002 percent on the

1000 psi weights.

The oil dead-weight gage readings are corrected for air

buoyancy on the weights, the local gravity, the thermal expansion

and elastic deformation of the piston and cylinder, and the barometric pressure as discussed in detail by Cross L 8J -

Estimates of accumulated pressure errors [3] are found in

Table 1 as a function of operating pressure.

2. Pressure Adjustment for Sample in Capillary

The static pressure created by the sample in the capillary

column of length L extending from the pipet to valves 9 and 10

must be subtracted from the observed pressure to obtain the true

pressure in the pipet. This static pressure head is given as m l e

For fluorine the factor ML 9/RTn varies from about 0.01 to 0.0001,

being less than 0. 001 for more than 95 percent of the data points.

F. Measurement of Temperature.

1. Instrumentation and Method

The temperature measurement and control system is shown

in Figures 10 and 11. A six-decade microvolt potentiometer is

used in conjunction with a 25 -ohm platinum resistance thermometer calibrated by the National Bureau of Standards. Lowimpedance, unsaturated standard cells are kept in insulated boxes,

providing large thermal inertia thereby reducing thermal fluctuations due to occasional temperature changes in the instrument

room (this change is usually of the order of ± 0. 5°C). There are

three different potentiometer current supplies, one for each section of the potentiometer. The smallest current supply of 12

microamperes is provided by a small cadmium cell located inside

the potentiometer, whereas the mid -section of the potentiometer

requires a current of 1 milliampere supplied from four 1. 35 -volt

mercury batteries connected in parallel. Six-volt lead -acid

batteries supply a current of 10 milliamperes to the upper potentiometer section. This latter current supply is stabilized by

connecting an isolated, rectified, and filtered alternating current

source across the batteries.

Stable current for the platinum resistance thermometer is

obtained from four 6-volt, 200 ampere-hours, thermally insulated,

and shielded batteries of low internal discharging type, connected

in series. This current is adjusted when flowing through calibrated standard precision resistors. The microvolt amplifiers are

coupled to 50 -microamperes panel galvanometers in suitable

damping and range -changing circuits. Spurious voltage effects

are reduced in the thermometer and thermocouple circuits by

soldering all junctions with a special cadmium-tin solder L9J resulting in negligible thermal electromotive force. All wires that

connect the cryostat to the instruments are carefully shielded to

avoid extraneous electrical noise and all apparatus and electrical

instruments are grounded with heavy copper conductors.

The regulation and control of the pipet temperature is

accomplished by balancing the cooling due to conduction down the

reflux tube with Joule heating in the 500 ohm constantan wire

heater. The potential across the platinum resistance thermometer, based on a thermometer current of 2 milliamperes used

for all measurements, is compared to the corresponding calibrated

value at the desired temperature set on the potentiometer. The

difference in potential is fed through a D.C. microvolt amplifier

to a power regulator L10] which adjusts the power input to the

heater to maintain the pipet at the desired temperature. With an

amplifier sensitivity corresponding to 0.0001 K, there is no
31

perceptible noise.

Regulation of the guard ring temperature, identical to the

pipet temperature, is accomplished in a similar manner with the

exception that the potential output of a differential thermocouple

between the guard ring and the pipet provides the signal that is

amplified and fed to the power regulator.

When standardizing, i. e. , adjusting the various potentiometer currents to give the correct voltage of the standard cell,

the power regulator input switch is opened and the steady-state

heating carefully adjusted by the power regulator control, so that

constant temperature is still maintained.

The meter damping and range -changing circuits connected

to the galvanometers are convenient when the actual potential

differences are to be read.

Uncertainties introduced in the thermometry are partly due

i\ to the specification of the potentiometer of 0. 01 percent of reading

plus 0. 02 microvolts, and partly due to the calibrated value of the

1 -ohm standard resistor of 0. 99999 ± 0. 00001 ohms. In terms of

temperature this amounts to a maximum of 2 millidegrees at 50 K,

increasing to 28 millidegrees at 300 K. Uncertainty due to the

calibration itself is probably less than 0. 002 K.

2. Thermometry Checks

Prior to the PVT experiments with fluorine, vapor pressures of ultra high purity (99. 99 percent or better) oxygen were
32

measured to check the accuracy of the thermometry. The observed vapor pressures. P , , are compared in Table 2 to those of the r r obs r

Agreement is within the specification of the pressure measurement

system, which indicates the thermometry to be of the desired

absolute accuracy.

The platinum resistance thermometer used was calibrated

according to the International Practical Temperature Scale of

1948 above 90 K and the NBS-1955 temperature scale below 90 K.

The temperatures of Table 2 are therefore reported on this basis

since the purpose of this table is comparison of data on the same

temperature scale. All fluorine data, however, were converted

in temperature to conform to the International Practical Temperature Scale (IPTS) of 19 68 by applying the temperature scale differ-
33

ences of Appendix A using the Aitken interpolation method [l2J.

These differences for temperatures below and above 90 K were

obtained from References L13J and L14J, respectively.

G. Safety Equipment.

Due to the hazards involved in handling fluorine at high

pressures, precautions have been taken to construct and install

equipment that would prevent fluorine gas from escaping into the

laboratory in case of an accident.

As mentioned, all system components handling fluorine,

i. e. , the cryostat, the gasometer, and the fluorine supply system,

are enclosed in aluminum cabinets and vented outside the laboratory by a separate ventilation system. The 0. 32 cm thick aluminum plates should give reasonable blast protection in case of an

explosion. In any case, the operator in the instrument room is

always separated from the high pressure fluorine system by an

explosion-proof wall. Also, all valves subject to high pressure

fluorine are operated remotely from this room.

Should a substantial system failure accidentally develop, the

fluorine may be discarded rapidly through two charcoal reactors

installed in parallel outside the laboratory. The reactors are

made of 9 cm diameter copper pipes lined with a layer of 1 cm

thick refractive cement since the reaction of fluorine with charcoal to form inert carbontetrafluoride, is extremely exothermic.
34

A vacuum system for pumping fluorine out of the PVT cell

(the pipet) and the gasometer flasks was also constructed. After

most of the fluorine is recovered in the booster, the remaining

fraction must be removed before a new run may be started. This

is done by pumping the fluorine through an alumina trap where

aluminum fluoride is formed and free oxygen is released through

the pumps „ Two pumps, one with fluorine compatible oil for the

initial pumping and another regular pump capable of producing an

even lower pressure, may either pump through the trap or by-pass

it.
35

IV. DENSITY MEASUREMENT

There are several volumes required for the density calculations. These are the volume of the gas in the gasometer system,

V , the volume of the pipet sample holder, V , and the different

g P

nuisance volumes of the gasometer manifold, valves and capillaries. The sample density, not including the corrections of

Equation (19), is given approximately as P V

P ~ MRT V ' { } g P

The subscript g refers to the gasometer system and M is the molecular weight of fluorine. Hence, the ratio V /V is an imporg P

tant factor affecting the density calculations.

A. Amount of Sample Measurements .

The term P V /MRT of Equation (2) refers to the actual

g g g

number of moles of fluorine contained in the pipet, the capillary,

and the diaphragm cell. This amount of sample may be determined through the previously discussed expansion process of the

fluorine into the appropriate glass flasks of the gasometer. To

get an accurate measure of the sample amount, it is necessary to

calibrate the glass flask volumes with utmost care.

1. Gasometer Calibration

The volumes of the l-,2-, and 6-liter flasks were calibrated

by weighing them with distilled water which had been boiled to re-
36

move any dissolved air. Calculations to obtain the actual volumes

involved corrections for thermal expansion and elastic stretching

of the glass itself and for air buoyancy on the flasks and weights.

Measurements of the flask volumes were also obtained by hydrogen

gas expansion from one flask or combinations of flasks to the

other flask or flasks. The volume of the 1 -liter flask as determined from the water weighings was selected as the standard

volume. Excellent agreement between volumes obtained from the

hydrogen gas expansion and the water weighings was observed for

the 2- and the 6 -liter flasks, while the volume of the 21 -liter

flask was taken as the mean of eight expansion determinations.

Comparison of these results are given in Table 3.

Nuisance volumes of the order of a few cm3 in capillaries, gasometer manifold, diaphragm cell, and the quartz bourdon tube were

determined through a combination of hydrogen gas expansions from

a calibrated volume of 128 cm3 and gas expansions between individual volumes

.
37

2. Adjustment for Sample in Capillary

and Diaphragm Cell

To obtain the actual density in the pipet as described in Section V. C. the amount of sample in the capillary and the diaphragm

cell, at the conditions of each P-T point, must be subtracted from

the total amount as obtained through the gasometry measurements.

Some pertinent data and correlations are necessary for these calculations:

a. The temperature of the diaphragm cell, Tj,

is measured using a calibrated thermistor as

one leg of a Wheatstone bridge (the temperature inside the quartz bourdon tube is measured in the same manner. )

b. The temperature T , corresponding to any

position at a fraction x of capillary length

extending from the guard ring at the pipet

temperature, T , to the top of the cryostat

at the diaphragm temperature, T -., is calculated using the thermal conductivity, K,

of stainless steel [l5], from
38

x

T,

K dT

K dT

(3)

An equation of state is needed to calculate

the compressibility factor, Z ., at any

pressure P and temperature T, in the

diaphragm cell and the compressibility

factor Z at any pressure P and temperature

T in the capillary. These are then used

to obtain the amount of sample in these

small volumes (the capillary volume, Vc ,

is 0.0682 cm3 while the diaphragm cell

volume Vi, including some other noxious

volumes on top of the cryostat, is 0.480 cm3

). A preliminary equation of state for fluorine

was obtained by fitting corresponding states

data calculated from oxygen, to the equation used by Prydz and co-workers [ 1 6] for

deuterium. After the new fluorine density

data had been corrected in this way, it was

again fitted to this equation for further

refinement. The data was then corrected
39

once more using the revised equation.

When this procedure was repeated for a

third time, no more significant changes

in densities were observed. Thus, the

amount of fluorine in the capillary is

B. Sample Volume Measurement .

The sample volume, which is only of the order of 26 cm3

,

is the volume of the pipet, V . Since it is inversely proportional

to the sample density, extreme care has to be taken to arrive at

an accurate value for this volume.

1. Determination of Pipet Volume

The volume of the normal pipet (volume at 20 °C and zero

pressure) was determined by means of hydrogen gas expansions
40

from the pipet to the 1 -liter glass flask. The expansion of gas

initially at 3. 5 to 5 MN/m2 in the pipet sample holder to this glass

flask resulted in a final pressure of approximately 1 atmosphere

in the entire system. Initially 'four determinations gave a mean

value of the normal pipet volume, V , equal to 25. 881 cm3. Later,

five redeterminations resulted in a value of 25. 879 cm3 for the

volume which is the value accepted for the normal volume at 20 °C

for the pipet. The latter value was adopted since greater internal

consistency, on the order of ± 0. 003 cm3

, was obtained among the

five measurements. Earlier measurements on the same pipet by

Goodwin L 3 j yielded a volume at 20 °C of 25. 907 cm3 or 0.11 percent higher than the volume of the current work. In his oxygen

work Weber L4J adopted a 0. 14 percent smaller volume of

25. 843 cm3

.

2. Thermal Expansion of Pipet

As noted, the normal pipet volume is a function of temperature. The volumetric thermal expansion of the pipet was obtained

using known relationships L17J for the expansion coefficient of

copper. Calculated values of the ratio of the normal pipet volume,

V° , at various temperatures to the normal pipet volume at 20 °C,

V , were fitted to a quadratic polynomial of the form

V°

X = -rjr =1.0 + a(T - 293. 15) + b(T - 293. 15)2 (7)
41

where

a = 5.9851 x 10-5

b = 8. 708 x 10-8

.

3. Elastic Stretching of Pipet

The relationship used to calculate the elastic stretching of

the pipet due to pressure given by Goodwin L 3 J "was modified to correspond more closely to experimental results on similar thickwalled vessels Ll8J. Thus, the corrected pipet volume at any

pressure P and temperature T , is given by

V = X (1. + c[l.O + d T ]P) V (8)

VI OPERATING PROCEDURE

A. Cleaning of Fluorine System.

Before the PVT apparatus was put together, each individual

component that would be exposed to fluorine was thoroughlycleaned. When it had been assembled it was passivated with

fluorine. The cleaning procedures were as follows:

1) Metal parts showing visible evidence of oxidation,

were submerged in a bath of 10 to 20 percent nitric

acid solution to remove the oxide film. The parts

were then rinsed with distilled water followed by

an acetone rinse and then dried with a dry nitrogen

or helium gas stream.

2) Metal parts showing no visible evidence of oxidation, were washed in trichloroethylene, followed

by an acetone rinse and then dried with dry nitrogen.

3) Polytetrafluoroethylene packings were flushed

with trichloroethylene and acetone followed by

a drying period under vacuum.

4) Specific items of equipment were obtained directly from the manufacturer ready for

fluorine service.
47

B. Passivation of Fluorine System.

The above cleaning procedures appear to have been satisfactory since no evidence of any reaction in the system was noted

during the subsequent passivation. This passivation was performed at a remote test site since experience in fluorine handling was

nonexistent at that time. Following is a description of the adopted

fluorine passivation procedure:

1) The system was flushed with dry nitrogen and

then evacuated for several hours to insure removal of all possible moisture.

2) The vacuum was broken with dry nitrogen and

the system was once more evacuated.

3) The vacuum was then slowly broken with

fluorine gas to a pressure of about 0.01 MN/m2

and the system was held at this pressure for

about 10 to 15 minutes. This was followed by

an increase in pressure in steps of approximately 0.03 MN/m2 until atmospheric pressure was reached. The pressure was then

raised in steps of 0. 2 to 1.4 MN/m2 to somewhat above the intended maximum operating

pressure and held at this pressure for

several hours.
48

The passivation and testing proceeded without difficulty.

C. Charging of Storage and Recovery Cylinder.

Before proceeding with any PVT measurement it was necessary to charge the storage and recovery cylinder with fluorine

from the fluorine supply cylinder. Before charging the cylinder

all valves (numbers of valves are given in Figure 2) were initially

closed. The subsequent charging procedure is as follows:

1) Open valves 1, 2, 4, 6, 7, 8, 9, and 18 and

evacuate the system up to valve 10.

2) Close valves 1, 2, 8, and 9.

3) Raise liquid nitrogen dewar around booster.

4) Open fluorine supply cylinder valve slightly.

5) Slightly open valve 1 and use valve 2 to regulate the flow of fluorine into the valve manifold, booster and storage cylinder. Condense the fluorine in the booster.

6) Close valves 1, 2, 4, and 7. Make sure valve 6

is open and lower the liquid nitrogen dewar

from around the booster, allowing pressure

to rise in the storage cylinder.
49

7) When the pressure reaches a maximum

(indicating that there is no more liquid

fluorine in the booster), close valve 6.

Repeat steps 5, 6, and 7 until the storage

cylinder pressure reaches a pressure of

2 to 2. 8 MN/m2

.

8) Close fluorine supply cylinder valve.

9) Raise liquid nitrogen dewar around

booster again and open valves 7, 1, 2,

and 4. Allow fluorine pressure in this

part of the system to drop to about

0.07 MN/m2 gage pressure by condensing fluorine in the booster.

10) Close valve 7.

11) Open valve 6 and lower the liquid nitrogen dewar from around the booster.

12) Close valves 1, 2, 4, and 18. Open valves

17, 16, and 8 and evacuate this portion of

the system.

13) Close valves 8, 16, and 17. The storage and

recovery cylinder is now charged with fluorine.
50

D. Charging of Pipet.

To charge the pipet so that a series of P-T data points maybe taken at the desired psuedo-isochore, the following steps are

performed:

1) Open valves 18, 15, 8, 9, 10, 11, 12, 13,

and 14 and evacuate the system.

2) Close valves 8 and 10.

3) Raise the liquid nitrogen dewar around the

booster and condense the fluorine in the

booster.

4) Close valve 6; open valve 7 and lower

the liquid nitrogen dewar from around

the booster allowing the pressure to increase in the PVT cell. When the desired

filling pressure is reached, shut valve 9.

5) Raise the liquid nitrogen dewar around the

booster. When the fluorine pressure

reaches a minimum, close valve 7 and

open valve 6. Lower the nitrogen dewar

again from around the booster.

E. The Data Run.

1. P-T Measurements

The pipet is now ready for data taking. Pipet pressures are
51

measured at integral temperatures on the IPTS 1948 and the

NBS 1955 temperature scales using the oil dead-weight gage. (The

temperatures were later converted to the IPTS 1968 temperature

scale as previously discussed. ) Data are taken at the same temperatures for isochores in the same region of the PVT surface

until either the maximum desired pressure (about 20 MN/m2

) or

the maximum temperature (300 K) is reached. Pressures are

measured at temperature intervals of 2 K from 54 K to 150 K.

Between 150 K and 200 K a temperature interval of 5 K is used,

while pressures are measured at every 10 K above 200 K.

2. Gasometry

As noted in Chapter II, the fluorine in the pipet must be

expanded into the gasometer to determine the number of moles

that were charged to the pipet originally. This is done as follows:

1) Close valve 15 and the appropriate valves

associated with the calibrated glass flasks

that are not to be used for the measurement.

This would involve valves 11, 12, 13 and 14.

2) Open valve 10 slightly and carefully allow the

fluorine to flow into the appropriate calibrated

volumes of the gasometer.
52

3) Record the pressure in the calibrated glass

flasks using the quartz bourdon tube gage.

For later experimental runs the air dead -weight

gage was used to measure this pressure, while

the quartz bourdon tube gage served as a null

indicator.

4) Close valve 6 and raise the liquid nitrogen

dewar around the booster.

5) Close valve 18. Open valves 7, 8, 9,

and 15 and condense the fluorine in the

booster.

6) Pump on liquid nitrogen around the booster

to reduce temperature in the booster to increase the recovery of fluorine from the

entire system. Close valve 7 when no

more fluorine is condensing as determined

from the quartz bourdon tube gage.

7) Open valve 6 and lower the nitrogen dewar

from around the booster when the solid

nitrogen has melted.

8) Open valves 16 and 17 and evacuate the system. When a pressure of 13 N/m2 is reached,

the trap may be by-passed by closing valves

16 and 17 and opening valve 18.
53

VII BURNETT EXPERIMENT

A. Apparatus .

The fluorine compressibility factor in the glass flasks must

be known to determine the amount of sample in the pipet from

gasometer measurements. This compressibility factor, PV/RT,

should be obtained at the water bath temperature of 295. 00 K as a

function of pressure. The gas expansion method introduced by

Burnett [z] in 1936 was used for this purpose.

The Burnett apparatus, shown in Figure 12, consists of a

heavy-walled AISI type 304 stainless steel bomb divided into two

vessels of unspecified volumes. Vessel number 1, approximately

53 percent larger than the second vessel, is directly connected to

a null pressure detector, which in turn is connected to the rest of

the pressure measuring system as described previously in Subsection III. E. 1. The two vessels are connected to each other by

means of a valve and capillary tubing. The apparatus, including

the null pressure detector, the valves, and the tubing is submerged in a constant temperature water bath controlled at

295. 00 K, the same temperature at which the gasometry measurements were taken.

B. Experimental Method and Analysis .

Initially, the first vessel was filled with gaseous fluorine to

the desired pressure of 2 to 3 MN/m2

, while the second vessel was

evacuated. The expansion valve was then opened and the pressure

allowed to reach equilibrium in the two volumes. Further expansions were performed until the final pressure was low enough to

allow extrapolation to zero pressure. More intermediate points

on the extrapolated curve were obtained by varying the initial

starting pressure for the expansions. Previous to the i expansion, the fluorine gas in the first vessel is described by the following conditions:

(PVJ. = R(ZnT). . (21) 1-1 1-1

When equilibrium is reached after the expansion, the equation of

state becomes:

P^Vj + Va ). = R(ZnT). . (22)

Since the temperature, T, of the water bath is constant and the

number of moles, n, also remain the same, T. = T. and

1-1 i

n. = n.. Hence, division of Equation (22) by Equation (21) yields

(23)

i-i

(Vx + Va )i N

i = ~w— (24 >

upon rearrangement

(

v Z ). -

l I Z J

where
56

N is therefore the ratio of the total volume of both vessels after

i the i expansion to the volume of the first vessel before this expansion. Thus, N. is called the cell constant of the i expansion.

1 Since the pressures before and after the expansion are different,

the change in the elastic stretching of the bomb results in a corresponding change in the volumes of the vessels. Consequently,

the cell constant is also a function of pressure.

By extrapolating P. /P. of Equation (23) to zero pressure

N m is obtained since Z. = Z. = 1 in the limit. The value obtained

l 1-1

for the zero pressure cell constant is 1. 65335 and was determined

by a least squares fit of a quadratic equation to these data. Thus,

since N^ is known, the value of N. at any other pressure may be

obtained by using the elastic stretching formulas of Roark L20].

These equations applied to this steel bomb, relate the change of

either volume from before to after the expansion as

AV/V = 2. 10 x 10" 5 (P. -P.) (25)

where P is in MN/m2

. Thus, even at the highest operating pressures of 3 MN/m2 this does not amount to more than a 0. 004 percent change.

Substituting values of (P/Z). for i = 2, 3, . . . . successively into the equation for the first expansion (i = 1), results in
57

P.N, N2 .... N.

where the subscript on the right-hand term denotes the starting

pressure for each series of expansions. The zero pressure limit

of P. N, NP . . . . N. is (P/ZL since lim Z. = 1.0. Values of

l i _ „ l P. -0

i (P/Z) for the different expansion series may, in turn, be substituted into Equation (2 6), which then relates the compressibilityfactor of fluorine at the water bath temperature as a function of

pressure. Analytically the results are represented as

Z(295. 00 K) = 1. - 3. 626 x 10 -3 P(MN/m2

) (27)

at relatively low pressures of a few atmospheres and are shown

graphically in Figure 13.

Since no other data were available for fluorine for comparison purposes, experimental runs were also performed using oxygen

and hydrogen to check for accuracy. These data agreed with published values [ll,2l] to within 0.005 percent. The agreement was

even better near atmospheric pressures, and provided confidence

that the fluorine compressibility data possessed similar accuracies.

VIII COMPUTATIONS FROM PSEUDO-ISOCHORES

A. Saturation Densities .

Saturation densities derived in this study were obtained byextrapolating the experimental isochores to their intersection with

the vapor pressure equation (Equation (32)) as discussed previously

L22j. By fitting the first few points of the experimental isochores

to low order polynomials, the intersection of the two curves was

obtained using an iterative procedure. The accuracy of the extrapolation depends on the vapor pressure equation, the length of

extrapolation to the intersection temperature, but mostly on the

difference in slope between the experimental isochore and the vapor

pressure curve. Thus the uncertainty of the intersection temperatures ranges from about 0. 001 K for saturated liquid densities near

the triple point, to more than 0. 1 K for saturation densities near

the critical density where the isochores become colinear with the

vapor pressure curve. These temperature uncertainties were used

to calculate the relative weight factor applied to each data point

(listed in Table 4) in fitting the saturation densities to the following

equation

T^T) = ,J>^L |3 p Aitep + V A,p-»]. (28)

is referred to Hust and McCarty [23j. Equation (28) was recentlydeveloped by Goodwin L24] for estimating the critical parameters of

pure fluids. These are obtained directly as the parameters resulting in the smallest variance between the experimental data and

this equation. Compared to the conventional methods this procedure

eliminates the need in this temperature range for fitting the saturated liquid and saturated vapor data separately, interpolating to

get the rectilinear diameter, and finally obtaining the intersection

of the saturation correlations with the rectilinear diameter. The

conventional method also requires better than 10" 6 percent accuracy in the saturated liquid and vapor representation to obtain an

accuracy of 0. 1 percent in the calculated saturated fluorine vapor

densities near the triple point. This requirement is estimated by

using Equation (28). Finally, accurate saturation data in the critical region are not needed as the form of Equation (28) is more

reliable in this region than the derived experimental data.

The experimental data above 120 K were fitted to Equation

(28) by the method of weighted least-squares and the critical parameters were selected as those which resulted in the smallest variance between the data and the equation. (Identical values for these

parameters were also obtained by analyzing the experimental data

using the conventional method). Only data above 120 K were used

since a better representation of the data in the critical region was
63

thus achieved.

When the estimated critical parameters (T c = 144. 31 K and

p c = 15. 10 mol/1) had been obtained, the saturated liquid and

vapor data were fitted to separate functions, each being constrained

to the critical point. This was done to obtain a better correlation

of the vapor density data near the triple point. The saturated

liquid density representation suggested earlier l24j was modified

so that no systematic deviations between the equation and the

experimental data were apparent. This new equation is as follows:

The coefficients resulting from this weighted least-squares fit of

the saturated liquid densities are

The number of significant figures given for these coefficients and

for those of subsequent equations is not justified on the basis of the

uncertainty of the data, but is presented to enable duplication of

the calculated values. Applied weight factors and the deviations

between the experimental and calculated densities are given in the

upper part of Table 4.

Similarly, all vapor densities were represented by the

equation suggested by Goodwin L24J

P \ r* (

Calculated saturated vapor data below 80 K were also fitted to

insure a representative equation that gives saturation densities

approaching the ideal gas value at the triple point (vapor pressure =

252 N/m 2

). These data were based on the vapor pressure equation

and an equation of state for fluorine L25j which represents the PVT

surface in this region to within the uncertainty of the data. The

following coefficients are obtained from this fit:

Cj = 4. 85547085

C 2 = -1.96015519

C 3 = -1. 88066900 x 10 _1

C 4 = 6.21165939

C 5 = -2.29600897 x 10 1
65

C 6 = 4. 69524623 x 10 1

C ? = -4. 30650270 x 10 1

In the final analysis, however, the thermodynamic properties were

calculated basing the saturated vapor densities below 6.

mol/1 (T = 137. 327 K) on the virial equation (34). Experimental data above 144. 31 K in Table 4 were used in Equation (28)

to estimate the critical parameters but were not used in Equations

(29) and (30) for obvious reasons (Z becomes negative). The reported temperatures in all equations (as discussed earlier) were

based on the IPTS 1968 temperature scale.

Saturated liquid density data from other sources [26, 27,

28, 29, 30, 3l] have been compared to Equation (29). All data

were adjusted, wherever possible, for temperature scale differences. These data were not, however, included in the final fit of

the equation as they deviate from the new data by as much as 28

percent in density (e. g. Kanda's density data LZ 6] are too low by

27-28 percent). Kilner et al. [27] report one density measurement at 77 K which is 1 . percent too low (their reported saturated

liquid density for oxygen is low by about 1. 7 percent). Saturated

liquid densities reported graphically by Dunn and Millikan [28] are

the same data for which Elverum and Doescher L29 J of the same

laboratory later reported numerical values. These data appear to

be about 0. 6 percent too high in density. The density data by
66

White, Hu and Johnston [ 30 J are the smoothest of the old data but

are too high by about 0.4 percent. Reported measurements by

Jarry and Miller L31J agree well with those of Reference L30j, but

they exhibit larger internal scatter (0. 3 percent). Early measurements of the saturated liquid density at the normal boiling point

[32, 33, 34J were also compared in this study. These data points

deviate considerably from the new data due to large uncertainties

in the temperature measurements as well as the density determinations.

No published saturated vapor density data exist but calculated values based on the Berthelot equation of state by Fricke L 35]

deviate from Equation (30) by as much as + 10 percent in density

at 140 K.

B. The Critical Point .

The critical temperature and density of fluorine estimated

from Equation (28) are given in Table 5. Also given is the critical

pressure obtained from the vapor pressure equation (see Equation

(32)). Critical parameters from other sources are also compared

to the new values in this table.

Fricke L 35 J calculated the critical density from the

Berthelot equation of state, while Baker and Adamson [ 3 6] used

the critical temperature from Reference [37] and obtained the

critical density by generalized properties techniques. Goodwin L24]
67

based his findings on the equation of state [25] that does not repre

sent the experimental data in the critical region well.

C. Melting Line Determination .

Fourteen pressure -temperature data points were measured

along the fluorine melting line during experimental runs no. 121

and 122 as reported earlier [38]. Measurements were made at

0. 1 K intervals from 1. 3 to 13. 7 MN/m 2

. These data, given in

Table 6, were fitted to the Simon melting equation

P = P t + P [(T/T t ) C

- l] (31)

where the subscript t refers to the triple point. By varying the

values of c and T t a best fit was obtained with the following
68

parameters

P t = 2. 52 x 10" 4 MN/m 2 (from Equation (32))

P = 249. 975 MN/m 2

c =2. 1845

T t = 53.4811 K.

Only two measurements on the normal melting point and none at

higher pressures have been made prior to this study. Hu, White,

and Johnston's [39] value of 53. 53 K agrees fairly well with the

new triple point temperature, whereas Kanda's L40J measurement

of 55. 2 K appears to be too high. The reason for the differences

may be due to impurities in the fluorine sample of the earlier

data or temperature scale differences.

IX VAPOR PRESSURE DETERMINATION

Fluorine vapor pressure data are reported in the literature by several experimenters [31, 39, 41, 42J. However, these

are inconsistent measurements covering the range from the triple

point to just a few degrees above the normal boiling point. To

insure accuracy in the subsequent thermodynamic properties calculations it was necessary to obtain consistent vapor pressure

measurements extending from the triple point to the critical point.

This was done using the PVT pressure measuring system together with the gasometer pressure gages as shown schematically

in Figure 14 [43].

A. Experimental Approach .

Pressures 'were measured by three different procedures

in overlapping ranges from the triple point to the critical point.

Pressures below about 0. 2 MN/m 2 were measured directly using

the fused quartz bourdon tube pressure gage previously calibrated

to the air dead-weight gage. Pressures above 0.003 MN/m 2 to

about 4 MN/m 3 were measured by referencing the fluorine to

nitrogen pressures derived directly from the air piston deadweight gage using a diaphragm type differential pressure transducer. Above 0. 13 MN/m 2

, pressures were referenced to the oil

dead-weight gage using two differential pressure transducers with

an intermediate nitrogen system separating the oil and the fluorine

for safety purposes.

Each vapor pressure reading was made at least twice at

a given temperature with some fluorine being removed from the

cell between readings. Identical pressure readings verified the

fact that two-phase conditions existed in the cell during a measure

ment.

B. Correlation of Vapor Pressure Data .

The fluorine vapor pressure data in Table 13 obtained as

a result of this work were represented by the following equation:

In ("^— ) = A X X + A 2 X

2 + A3 X3 + A4 X (l-x) As

(32)

where

X = (1 - T t /T)/(1 - T t /T c ) P t = 2. 52 x 10~ 4 MN/m 2

T t = 53.4811 K

T c = 144. 31 K

The subscripts t and c refer to the triple point and the critical

point, respectively. A trial and error method was used to select

the value of the triple point pressure which resulted in the smallest sum of the squared deviations between the data and the corresponding calculated values. Changes in this pressure of the

order of 0. 5 percent were directly reflected in larger deviations

all the way to the critical point. The obtained value agrees well
73

(0. 3 percent) with the pressure calculated by Ziegler and Mullins

L44]. Equation (32) was recently developed by Goodwin L45J through

a comprehensive study of vapor pressure equations. It is nonanalytic at the critical point, i. e. , the curvature is infinite, and

exhibits a reliable slope dP/dT over the entire liquid range, a

requirement that the polynomial type equations do not always meet.

The coefficients, A.'s, of Equation (32) were determined

by a least-squares fit of the experimental data in Table 13. An

iterative procedure was adopted such that the chosen value for A 5 minimized the weighted sum of the squared deviations. However,

this value of A5 must be between 1. and 2. to give infinite curvature at the critical point. The selected coefficients for the vapor

pressure equation with P in MN/m 2 and T in degrees K, are

A3. = 7. 89592346

A2 = 3. 38765063

A3 =-1. 34590196

A4 = 2. 73138936

A 5 = 1.4327 .

All parameters of this equation are significant at a level better

than 99. 9 percent when the standard F-test is applied.

The weight factors, W, in the least-squares fit were defined as the inverse of the sum of the variance in pressure and an

equivalent variance, defined according to the error propagation
74

formula, due to errors in temperature. Hence,

w =

'-

3 ( 3P \ 2

where a

2 and a

2 are the respective variances in pressure

and temperature.

C. Discussion .

The experimental data are compared to the vapor pressure equation in Figure 15. Pressure deviations are defined as

(P - P . ) x 100 /P , where P is the experimental

pressure and P , is the value calculated from Equation (32). calc

Data by other experimenters L 37, 39, 4 1 J were adjusted in temperature whenever possible to conform with the IPTS 1968 temperature scale and compared to the new data in Figure 15. Rigor

ous calculated values L44J based on thermodynamic data such as

latent heats due to phase changes, heat capacity and mean molal

volume of the liquid, etc. and fluorine molecular constants L46j

are also compared in this figure. However, the data from these

sources were not included in the final fit of the vapor pressure

equation since they deviate from the new data by as much as 1 6

percent. These large deviations are partly due to problems

involved in the early fluorine vapor pressure measurements,

which involved reaction of fluorine with mercury in the glass

fluorine sample. The data by Claussen L42J were not considered

as they were given in terms of a vapor pressure equation. Deviations of the data from this equation were reported to be as much

as 2. 5 percent.

No previous measurements of fluorine vapor pressure

exist above 89.4 K, but values given by Landau and Rosen L47]

obtained by extrapolating the data of Cady and Hildebrand [37] to

higher temperatures, appear to be in error by as much as - 15

percent.

By interpolating the data in Table 7 directly, a normal

boiling point temperature of 84. 95

± 0. 003 K on IPTS 1968 was

obtained. This agrees well with published values of 85. 03 K L39J

and 84.95 K L37J, corrected for temperature scale differences.

Calculated vapor pressures L44J are based on the normal

boiling point of L 39 J and hence agree well with that data in this

region, but they deviate by as much as + 15 percent from [ 39 J at

the triple point.
77

X REPRESENTATION OF SINGLE-PHASE PVT DATA

All experimental single -phase PVT data in both the compressed liquid and vapor regions are given in Table 14. The

column of this table labeled "IDENT" contains the identification

number of each data point. The last two digits represent the

point number while the remaining digits are the number of the

run or experimental isochore. Entries in runs 120 and 121 which

contain no value for the density are pressures measured on the

melting curve.

Some attempts were made to fit this data with an equation

of state used successfully for other cryogenic fluids L25J. However, this equation was not capable of representing the data to

within its precision, a fact particularily evident in the critical

region. Therefore, to obtain the best possible representation of

all the data, it was decided to divide the PVT surface into two

regions as pictured in Figure 16. The data in each region were

correlated separately as discussed below. No other published

single -phase fluorine PVT data were available for comparison to

the new data.

A. Low Density Region .

Experimental PVT data of densities less than 0.22

mol/1 were obtained indirectly as gasometer measurements

at these low densities were not possible. Pressures were

obtained using the air dead -weight gage while the density was derived by heating the PVT cell to 175 K using the known pressuredensity relationship for that isotherm. These data together with

all other experimental PVT data below 6. mol/1 in density were

represented by the truncated virial equation

P = RT [p+ B(T)p 3 + C(T)p 3

] . (34)

The second and third virial coefficients were expressed as a

function of temperature by

(34a)

and

6

C(T) = V C. x

, (34b)

i=l

respectively. An iterative method was used to optimize both the

number of coefficients of B(T) and C(T) and their temperature

dependency.

The decision to use 6. mol/1 as a maximum density

value for the virial surface was based on the results obtained by

fitting the experimental data to Equation (34). By varying the

maximum experimental density included in the fit of this equation,

the data exhibited definite systematic deviations from the equation

in density as well as temperature for all maximum densities
80

greater than 6. mol/1. Equation (34) was based on the 329 PVT

data points in the virial region. Further, 2 6 experimental single

phase specific heat (C ) data points L48J between 6. 5 and 6. 8 mol/1

at temperatures from 140 K to 300 K were compared to extrapolated

C values calculated from the virial equation. The reason for this

was to ascertain that the apparent deviations were fairly constant

and not a function of temperature. The coefficients of Equations

(34a) and (34b) and their significance level obtained through a

weighted least-squares fit of all the PVT data in this region are

given in Table 7. Weight factors [23J used in the fitting of Equation (34) were similar to those used for the vapor pressure equation

(32), except variances in density were also considered. PVT data

below 100 K were weighted much lower than above this temperature

as the uncertainty of the measurements in this region increases

rapidly with decreasing density. The weighted standard deviation

in density between the virial surface and all of the 329 PVT data

points is 0. 041 percent. For consistency, Equation (34) was constrained to give the same saturation temperature (137. 327 K) for

the 6. mol/1 isochore as is obtained from Equation (30).

The second and third virial coefficients, calculated from

Equations (34a) and (34b), are given in Table 8. Also given in

this table are the quantities &B and 8C which are the respective

estimated uncertainties of the coefficients based on the experience

gained when fitting the virial surface. A comparison of the second

virial coefficient with values obtained by White, Hu, and Johnston

L49J is given in Figure 17. In the calculation of their data these

authors neglected the contribution of the third and higher order

virial coefficients, which is the probable reason for their larger

negative values, especially at lower temperatures. Temperature

scale differences could account for part of the deviations. Since

the data from Reference [49] do not represent just the second

virial coefficient, further comparisons with Equation (34a) were

made by converting values from oxygen L4J and argon L 50 J using

the corresponding states approach based on critical parameters

as follows:

Pc (X)

B„„„„_.^ = B(X) converted p c (F g )

and

T , = T(X)

T c (F a ) converted Tc (X)

where X represents either oxygen or argon. The agreement is

good as may be seen from Figure 17. In fact, the correspondence

between values calculated from the second virial coefficient of

oxygen and Equation (34a) is better than one may justifiably expect

from the principle of corresponding states.

No published values for the third virial coefficient of

fluorine were available for comparison to Equation (34b).

The high density region (see Figure 16) bounded by the

Data points for a fictitious liquid isotherm at 53.4 K, used for the

purpose of extrapolating to the melting curve, were obtained from

an extrapolation of isobars calculated from the isotherms between

56K and 64 K. A few points on the 54 K isotherm were also obtained in this manner. The density of the liquid in equilibrium

A value of 44. 86- mol/1 was used for the liquid density, p t ,

at the triple point.
86

No more than 3 coefficients were used for the isotherms

below 60 K since these consisted of only 4 P-p data points each.

As many as 9 coefficients were necessary for the 146 K and 148 K

isotherms (slightly above the critical temperature) to adequately

represent the data. From 4 to 7 coefficients were needed to represent all of the remaining isotherms. The isotherms in the

compressed liquid and gaseous phases below the critical temperature were constrained to the corresponding saturation density of

Equations (29) and (30), respectively. Above 138 K the isotherms

were also fitted to the low density data in the virial region to provide a better match of the surfaces around the 6. mol/1 isochore.

The standard deviation of the 381 experimental data points

in the compressed liquid was only 0. 005 percent in density while the

540 compressed vapor data points exhibit a larger deviation of

0. 018 percent. The latter value is higher due mainly to the contribution from the isotherms just above the critical temperature where

the deviations are much larger than over the rest of the surface.

However, this is what one normally would expect.

2. Isochores

Most calculations of thermodynamic properties require

knowledge of the quantities (dP/dT) and (3

2 P/dT 2

)

. In the low

P p density region these derivatives may be calculated directly from
87

Equation (34) while for densities above 6,0 mol/1 it was necessary

to calculate pressures at even density increments. These isochores

were then represented using functions of the form

n

P = V A. T

(38)

Is 1 i="l

Density increments of 0. 5 mol/1 were used for the 80 isochores

between 5. 5 and 45. mol/1. The number of terms of Equation (38)

varied from 7 at the lowest density to 3 at the 45. mol/1 isochore.

The good fit of the isotherms was directly carried over in the

correlation of these isochores.
XI DERIVED THERMODYNAMIC PROPERTIES

Additional data to the PVT measurements are necessary in the

calculations of derived thermodynamic properties. These are

mainly thermodynamic functions of the ideal gas; however, specific heat data of the single-phases and the saturated liquid also

help to improve the accuracy of the calculations.

A. Thermodynamic Functions of Ideal Gas .

Since new measurements of the dissociation energy of

fluorine L 5 1 J recently became available, it was decided to recompute the ideal gas thermodynamic functions of this fluid. Maximum

changes in the functions compared to earlier values 1.46] were less

than 0. 1 percent for temperatures of 300 K and below. These

thermodynamic functions were calculated according to the statistical mechanical treatment of Mayer and Mayer L 5Z J for diatomic

molecules. The relationships based on their approach include first

order corrections to the harmonic oscillator -rigid rotator for:

vibrational anharmonicity, rotational stretching, and rotationvibration interaction. No attempt will be made here to define all

different parameters. The conventional nomenclature for these

variables may be obtained from standard texts l52, 53j. The

correlations are as follows:

Finally, values of entropy were computed from the following relationship

S°/R = (H° - Hg)/RT - (F° -H°)/RT. (53)

The variables a, u, 6, y> an-d X were calculated from

the new measurements of the dissociation energy of fluorine L 5 1 j

and the Raman spectrum measurements of Andrychuk L54J.

Table 9 list some representative values of the ideal gas

functions used in the calculations of the thermodynamic properties

of fluorine. Further checks on the ideal gas enthalpy, H°, and

entropy, S°, were obtained by numerically integrating the ideal

gas specific heat at constant pressure, C°p (Equations (41, 45, 49))

and C p /T as functions of temperature, respectively. All deviations from the values given in Table 9 were less than 0. 001 percent. Hq was taken to be zero in all calculations.

B. Calculational Methods .

Obviously no integration with respect to density of the

thermodynamic equations was possible until a final density was

determined for a given temperature and pressure. This was. done

by an iterative process of the virial equation for densities below

6 . mol/1 and of the isotherms for densities above 6 . mol/ 1 .

Once the density had been established, the calculations were per

formed using the following equations.

For densities less than critical at T less than

T2 (= 160 K) and for all densities for T 2: T2 , the thermodynamic

properties were calculated as follows:

The ideal gas properties for enthalpy, entropy, and specific heat,

H° , S° , and C°(- C° - R), respectively were obtained from

Equations (39) through (53). All integrations in the high density

region of Figure 16 were carried out numerically using the

trapezoidal rule. For the development of these and the following
93

equations the reader is referred to References L55, 56].

For densities greater than the critical between temperaatures T1 = 135 K and T2 = 160 K the starting points for the calculations are taken as those calculated from the above equations at

T2 and a density Pl - 26.4276 mol/1. The specific heats along this

isochore, given by Equation (69), were used to compute the changes

in properties as a function of temperature:

H(T, Pl ) = U(T 2 , Pl)+ C V(T, Pl )dT + P(T, Pl )/ Pl , (57)

For the compressed liquid at temperatures less than T x (= 135 K)

use was made of the properties of saturated liquid at (T 1} p-^) as

a starting point for the computations. Changes in properties

along the saturated liquid curve were calculated from the following

equations:

H(T, p sat L ) = H(T 1} p satL ) + j C sat dT

and

C v (T, PsatL ) = C sat (T) +

n 3 Psat L

dp sat L dT

5P

3T (65)

Since the integral of Equation (64) cannot be solved analytically and since (l/p sat L ) was not correlated as a function of the

vapor pressure, these integrals were obtained numerically.

C sat (T) is the saturated liquid specific heat as discussed in the

following section and given by Equation (68). Further computa-
95

tions in the compressed liquid region along isotherms were made

using Equations (60), (61) and (62) in which p satL (T) was substituted in place of p 1

.

Calculations of internal energy and specific heats at

constant pressure were performed using

U(T,p) =H(T, p) - P(T, p)/p, (66)

and

C P (T, p) = CV (T, p) + (T/p 2 )(3P/3T)2 /OP/Sp) T

. (67)

C. Specific Heat Data Used

Specific heat measurements of fluorine L48, 57], recentlycompleted in this laboratory, were used to improve the accuracy

of the thermodynamic properties and make the thermodynamic

calculations more consistent. In the calculations for the compressed liquid and the compressed gas below 1 60 K use was made

of the specific heat of saturated liquid L57J, C sat (this quantity

does not include the specific heat of the corresponding saturated

vapor), expressed in the following form

A 8 1

C„t (T) = A1 (T C - T) + ^A.T 1 " 3. (68)

i^3

The coefficients for this equation are given in Table 10. The

root-mean square deviation of the 34 C sat data points between the

triple and the critical point is 0. 11 percent.
96

C measurements by Prydz and Goodwin L48J along an

isochore of density pj_ = 26. 4276 mol/1 were also used for

the thermodynamic properties calculations. Since the C v data

close to this density were measured at pseudo-isochores, the data

points were adjusted to p x using the experimental PVT data in this

region according to Equation (62). This C isochore intersects

the liquid saturation boundary at a temperature of 135.000 K (T x)

and the 1 60 K (T a ) isotherm (T s = 160. 010 K on IPTS 1968) at a

pressure of 20. 8 MN/m 2

. Analytically, these specific heat measurements at the p l - isochore were represented by

4

C v ( Pl )= I AJ 5 " 3 (69)

i=l

where the coefficients are given in Table 10. To obtain even more

consistent results, Equation (69) was constrained at C v (T l5 px )

= 28.282 J/mol as calculated by the following expression

Ti r (

d psat L \ i bp

C.fT,, Pl ) = C sat ( Tl ) + — !(^j^)(^yPi Pl

T

• (70)

Equation (69) was based on 20 adjusted (to p x ) experimental C v

points which exhibit a root-mean-square deviation of 0. 09 percent

when the equation is constrained. Prior to constraining Equation

(69) the value of C V (T 1 , p x ) calculated from this equation (Eq. (69))

was about 0. 2 percent less than that obtained from Equation (70).
97

This is certainly within the accuracy of C sat (135 K). Further,

the quantity (d p sat L /dT) is the temperature dependency of the

saturated liquid density (Equation (29)) and (BP/3T) is the terPi

minal slope of the p -isochore at the vapor -liquid coexistence

boundary. These slopes cannot be estimated with confidence by

extrapolating the PVT data because the isochores in this terminal

region may have maximum curvature. Considering that C sat is

about 3C at T1 (135 K) and that the bases for the thermodynamic

properties calculation are Equations (68) and (65) below T1 while

Equation (69) is used as a starting point above this temperature,

the reason for constraining Equation (69) becomes self-evident.

D. Calculated Results.

Calculated points on the Joule -Thomson inversion curve
98

are given in Table 11. This curve is defined as the locus of

points where the Joule -Thomson coefficient is equal to zero.

This condition may be described in classical thermodynamics by

the relationship

or more conveniently

*(tf-)p -(!f)T

-

Equation (72) may be solved by an iterative technique using the

isotherm derivative, (3P/dp)T , and the isochore derivative,

(dP/dT) , obtained from Equations (35) and (38), respectively.

The computed pressure errors in Table 11 are based on an

assumed uncertainty of 1 percent in these derivatives.

Tables 15 and 16 present the results of all thermodynamic

property calculations on the vapor -liquid saturation boundary and

on selected isobars, respectively. The velocity of sound, Ws

, was

calculated from the following relationship

Ws = [(C P /CJ OP/9p)T

] 1/2

. (73)

The variation of C p with temperature along several isobars

is illustrated in Figure 18, while Figure 19 shows the density

dependence of C along various isotherms.

E. Discussions Concerning the Derived Properties.

The best estimates of the accuracy of the derived thermodynamic properties are obtained by making comparisons with experimental values for these properties. In general, though, such

data are often scarce, limited in scope, or of poor accuracy. In

the case of fluorine, thermodynamic property data are practically

nonexistent.

Internal consistency checks may be made by performing

closed loop computations for different regions of the PVT surface.

Because of the somewhat roundabout method used to calculate the

enthalpy of the liquid as described in Section B of this chapter, it

is particularly desirable to make comparisons with liquid enthalpies

obtained by different methods. This may be done by comparing

heats of vaporization reported by different sources as given in

Table 12. The second and third columns of this table present

values of AH and TAS obtained from Table 15. The differences

between these two columns need to be explained. AH should not

differ from TAS by more than a few J/mol if all correlations used

for the computations provide the "true" value for a particular

variable. An error offset in the vapor pressure at the triple point

of 2 percent would alter the TAS value at this temperature by

9 j/mol due to a change in the entropy value of the vapor as a result of the R In (RTp/P ) term in Equation (55). Obviously, AH in

the second column of Table 12 would not be altered. The differences, however, may also be due to errors in the saturated liquid

specific heat, C sat (Equation (68)). An average error in C sat of

-2 percent between 53. 5 K and 135 K would change AH at the triple

point temperature by about -103 j/mol and TAS by approximately

-60 J/mol, resulting in a net difference of essentially 43 J/mol.

Other heats of vaporization in Table 12 are calculated by the

Clapeyron equation

AH = T(V^ - V^) -f| , (74)

where (V*, - V ) is the difference in the molar volumes of the

saturated gaseous and liquid phases and dP/dT is the slope of the

vapor pressure curve. These AH - values, however, suffer from

relatively large uncertainties in dP/dT and Vo, at low temperatures. Calculations by Ziegler and Mullins [44J agree well with

the new data (AHcl ) near the triple point but the deviations increas

as the temperature approaches 85 K. This is to be expected since

Ziegler and Mullins' vapor pressures are based on the normal

boiling point of Reference L39J, as may be noted from Figure 15.

Fricke L35j based his AH - calculations on the Berthelot equation of

state which gives vapor densities differing from Equation (31) by as much as 10 percent at 140 K.

The entropy value of the saturated liquid at the triple point

calculated using the method described in Section B of this chapter,
105

is 60. 862 J/mol K. Hu, White, and Johnston [ 39] report a value

of 61. 028 ± 0. 25 J/mol K based on their solid fluorine calorimetric data. More recent calculations by Ziegler and Mullins [44j

resulted in 60. 777 J/mol K, the difference being attributed primarily to improved calculations of the entropy change in the extrapolated region from - 14 K. In any case, it may be concluded

that the agreement among the three values is consistent with the

Third Law of Thermodynamics. Thus, the TAS values are more

likely to represent the correct values of the heats of vaporization

since large errors in the vapor pressure equation are not probable.

Experimental specific heats, C , measured by Prydz

and Goodwin L48] agree well with values calculated from the PVT

surface for densities above the critical and temperatures below

160.01 K. This is to be expected since the calculated specific

heats in this region of the PVT surface were based on the experimental values for C [48] and the Caat measurements of Goodwin and

Prydz [57j. Over the rest of the surface the measured C values

are larger than the values calculated from the PVT data. The

disagreement is within the combined uncertainty of the two experiments, although at high pressures (20 MN/m2

) and 160. 01K maximum discrepancies of about 3 percent in C are apparent.

Calculated specific heats at constant pressure, C p

, are not

as smooth as may be desired. These quantities are based on the
106

ratio of the square of the isochore derivative, (dP/dT)2

, to the

isotherm derivative, (dP/dp) T

, which are not likely to be completely smooth in the terminal regions of the PVT surface. In these

regions a density error of 0. 01 percent can result in relatively

large errors in the slopes. Also, the integration of the second

derivative of the isochores as indicated by Equation (62) increases

the probability of a somewhat erratic behavior. The actual values

of the Cp's, however, should be as accurate as may be calculated

from an equation of state and indicate better what uncertainty in

the computed values may be expected from the calculations.

No experimental sound velocities for fluorine have been

reported in the literature. However, the divergence of C which

has been observed for several fluids, including fluorine [48j, near

the critical point, implies the vanishing of the isentropic sound

velocity as proposed by Yang and Yang L58J. Recent measurements

by Barmatz L59j on He4 also show similar behavior. Calculated

velocities of sound for fluorine presented in Tables 15 and 16, tend

to indicate such a trend.
107

XII CONCLUSIONS

An apparatus has been constructed and used successfully

to measure about 150 vapor pressure data points and more than

1000 PVT points for fluorine from the triple point to 300 K at

pressures to about 24 MN/m2. The problems associated with the

high reactivity and extreme toxicity of this element which impose

severe requirements on system compatibility and provisions for

personal safety, were solved.

A network of isotherms and isochores and a virial equation were adopted to represent all PVT data. These equations

represent the data to within its precision, -which is of the order

of 0. 05 percent in density over the whole PVT surface. The

actual accuracy of the densities predicted from the equations is

estimated to be about 0. 1 percent. Uncertainties in the temperature and pressure measurements are about 0.01 percent, increasing somewhat in the lower terminal regions. In the critical region

the densities obtained at various pressures are necessarily less

accurate because of the high isothermal compressibility. However, even though the nonanalytic character that causes the

specific heats to diverge in the vicinity of the critical point has

not been included in the form of the isotherm and isochore equations, tabulated values of the derived properties given in Tables

15 and 16 are believed to qualitatively show the right behavior in
108

this region. However, caution should be exercised near the critical

point when extrapolating or interpolating on the derived properties.

This is particularly true for both the heat capacities and the velocity of sound since these properties supposedly exhibit anomalies

in this part of the surface.

Due to the fact that this study is relatively complete (it

is also based on experimental specific heats), it is believed that

measurements from only a few other experiments would help to

confirm or improve the accuracy of the PVT data and the derived

properties. Some additional measurements utilizing other experimental techniques [60, 61, 62] covering selected portions of the

surface would be valuable for the purpose of checking the accuracy

of the PVT correlations obtained in this study. PVT measurements

covering the critical region would also help to improve the surface.

Such data were recently obtained by Weber L63J in his critical region

studies of oxygen by means of dielectric measurements. Corresponding measurements for fluorine would be possible since a compatible insulating material for the electrical leads entering the

pressure bomb, has now been found [ 64 J . Thus, the critical parameters could be evaluated with a technique that is more accurate

than the one used in this study. Finally, very accurate (preferably better than 0. 1 percent) experimental heats of vaporization

measurements would help to clarify as to which AH - column in

Table 12 gives the more correct values.
