Title: Process for the manufacture of monofluorophosphoric acid and its monoesters
IPC: C07F9/14
Filed: 1965-12-14
Abstract: Monofluorophosphoric acid esters are prepared by reacting a monoester of H3PO4 or a monoester salt of H3PO4 with HF in the presence of trichloroacetonitrile and/or dicyclohexyl-carbodiimide and a tertiary aliphatic amine and/or a heterocyclic base containing tertiary N as acid binding agent.  The product may be hydrolysed and isolated as an alkli metal, e.g. Na, K, Li or NH4+, salt or cyclohexylammonium salt. The reaction temperature may be -10 DEG  to +150 DEG  C.  Binding agents specified are pyridine, collidine, lutidine, trimethyl, triethyl or tributyl amine.  The ester group may be alkyl, aryl or aralkyl, normally containing not more than 25 C atoms, e.g. nucleosides.  The reaction may be performed in a solvent, e.g. acetonitrile pyridine or dimethylformamide and the HF may be in aqueous solution.  The product may be purified by ion exchange. When ribo-nucleotides are reacted with HF and trichloroacetonitrile, 21,31-O-(1-trichloro-2-amino) - ethylidene - nucleotides are formed along with the monofluorophosphate.  The former compounds, with dilute acid at room temperature form nucleoside-51-monoflourophosphate in quantitative yield.  Under alkaline conditions the reaction is slower, further hydrolysis with stronger bases yields nucleosides and nucleobases.  Specified nucleotides are adenosine-, uridine- and guanosine-51-phosphates.ALSO:Monofluorophosphoric acid and its esters and salts, e.g. alkali metal or NH4+, are prepared by reacting H3PO4, a mono ester of H3PO4 or a salt of phosphoric acid or an ester thereof with HF in the presence of trichloroacetonitrile and/or dicyclohexylcarbodiimide and a tertiary aliphatic amine and/or a heterocyclic base containing tertiary N as acid binding agent.  The product may be hydrolysed and isolated as an alkali metal, e.g. Na, K, Li or NH4+ salt or cyclohexylammonium salt.  The reaction temp. may be - 10 DEG  to + 150 DEG  C.  The binding agent may be a tertiary amine, e.g. pyridine, collidine, lutidine, trimethyl, triethyl or tributyl amine.

The reaction may be performed in a solvent, e.g. acetonitrile, pyridine or dimethylformamide, and the HF may be in aqueous solution.  The product may be purified by ion exchange. Using free H3PO4 and excess HF and condensing agent polyfluorinated, e.g. difluorophosphoric, acids are obtained and may be hydrolysed, preferably in weak alkaline medium, to the monofluorophosphoric acid salt.

In the carrying position shown in Fig. 1 the container 10 is further secured by a manually operated spring-loaded hold.down 9 at the upper end of link 5 of one of a pair of scissors lifting links 4, 5 on either side of the frame 1. The catch 8 is attached to the upper end of the link 4 and includes a latch 13 pivoted on a pin 13<SP>1</SP> and biased to the closed position by a spring 15. The latch 13 is operated by a lever 19, pivoted on a pin 19<SP>11</SP> which passes through an arcuate slot S in the latch itself, through a pin 23 engaging face 20 an the latch 13. The lower end of the lever 19 has a pin 19<SP>1</SP> from which a cable 24 extends to a pin 5<SP>11</SP> on the link 5. When the container 10 is lowered by retracting lifting jacks 6 the cable 24 is tensioned to open the latch 13 to the position shown in Fig. 2 and release the container 10. Conversely, lifting the container 10 allows the latch 13 to close. The arcuate slot S enables the latch 13 to be opened manually when it is in the closed position due to the container 10 being raised. The lower end of the link 5 is pivoted at 1<SP>1</SP> on the frame 1 while the lower end of the link 4 is mounted on a roller 4<SP>1</SP> engaged in a channel 7. If the container 10 is lifted past the carrying position shown, further lifting results in the container 10 being tipped since the link 5 is longer than the link 4.

Abstract: 1456029 Position encoding WESTING- HOUSE ELECTRIC CORP 28 Dec 1973 [3 Jan 1973 (2)] 59943/73 Heading H3H The position of a nuclear reactor control rod is sensed by two interleaved sets of sensor coils A, B, Fig. 3A, connected to respective encoders 18 which compare the currents through each pair of adjacent coils in the same set to find the location of the end of the drive rod, and convert this into binary gray code. Encoder, Figs. 4A, 4B.-Each sensor coil a to u is connected in series with a resistance 200- 240, the resistances of the end coils a, u being of different values to resistances 200-236 to compensate for end effects. Differential amplifiers 242 with transient-limiting diodes and filters 32 produce a controlling D.C. voltage on that one of capacitors 264-304 corresponding to the position of the end of the rod, and the inversion of the required gray code appears at the bases of transistors 318-326. When addressed from central control, the encoder transmits gray code bits α, #, γ, #, #. In the event of an open or short circuited sensor coil, resistor or diode, an excess voltage results at the common of the sensor coils which is detected by circuit 34 which disables NAND gates 330-338 so that all the output bits become logical 1 which the central logic circuitry will interpret as a fault indication and signal back to the encoder a low frequency pulse signal F to cause a red light-emitting diode 368 to flash.  For a reactor having many control rods, each with sensor coils A, B, all the A coil signals and all the B coil signals are time-division multiplexed into respective A and B channels, transmission of the position signals and the addressing signals being via optical isolating links. The received signals are checked, Figs. 7A, 7B (not shown) for error indicating combinations and compared with each other to see if a difference error exists, and are converted to normal binary form. If no error exists, the A and B signals for each rod are combined and decoded to energize an appropriate light emitting diode to indicate the rod position to the full resolution of the system. If an error is detected in the A or B channel only the good channel is used, the resulting indication being to half the resolution of the system. The central logic may be triplicate and use majority voting.
