Title: Production of aromatic from naphthenic hydrocarbons
IPC: C07C5/387
Filed: 1943-07-12
Abstract: Aromatic hydrocarbons are produced by contacting hydrocarbon vapours consisting predominantly of non-hydroaromatic naphthenes of at least 6 carbon atoms under "dehydroisomerization conditions" with a molybdenum oxide catalyst. "Dehydroisomerization conditions" necessary to dehydrogenate and isomerize the naphthenes to aromatics are defined as temperatures of 450-550 DEG  C., pressures of 2-60 atm., liquid hourly space velocities of 0.1-2, and hydrogen partial pressures of 1-50 atm.  Methyl cyclopentane yields benzene, C7 naphthenes such as dimethyl-and ethyl-cyclopentane yield toluene, and C8 naphthenes give xylenes.  Straight run distillates, for example boiling at 150-223 DEG  F., from naphthenic petroleums may be fractionated to obtain methyl cyclopentane fractions, for example of boiling range 150-185 DEG  or 150-170 DEG  F.  Dimethyl cyclopentane fractions may, in some cases, be separated from gasolines similarly. Suitable feedstocks are also obtainable by catalytic dehydrogenation of fractions containing the desired non-hydroaromatic naphthene to dehydrogenate the hydroaromatic naphthenes present to aromatic hydrocarbons, extraction of these, and removal of paraffins by extraction or cracking or dehydrocyclization followed by fractionation or extraction.  The molybdenum oxide may be used alone or with promoters, carriers, and diluents.  Preferably about 4-30 per cent is appied to an absorptive carrier such as active carbon, magnesia, clay or alumina.  Active alumina may be stabilized by mixing with clay or conversion of at least the surface into a spinel structure by reaction with calcium or magnesium oxide or the like. Suitable reaction conditions using the preferred catalysts are 490 DEG  C., 15 atm., 0.5 hourly space velocity, and 7 atm. hydrogen partial pressure.  The vaporized naphthene with 2-5 volumes of hydrogen may be passed over the granular or pelleted catalyst.  In examples, methyl cyclopentane is passed with 5 or 3 volumes of hydrogen over a molybdena-alumina catalyst (14 per cent Mo) at 490 DEG  C. and 20 or 10 atm. total pressure, contact times being 100, 50 or 30 secs. and space velocities 0.26, 0.16, 0.32 or 0.53; and a 88-93 DEG  C. fraction separated from a naphthenic straight run petroleum fraction and consisting of dimethyl cyclopentanes with some paraffins and methyl cyclohexane is similarly converted using the same catalyst and temperature with a pressure of 10 atm., contact time 100 secs., hourly space velocity 0.2, and hydrogen to hydrocarbon ratio 3 or, when the pressure is reduced to 5 atm., a space velocity of 0.1.

Title: Improvements relating to soot-blowers
IPC: F28G3/16
Filed: 1958-04-10
Abstract: 848,771. Soot-blowers. WILSON, P. M. April 9, 1959 [April 10, 1958], No. 11336/58. Class 99(2). A pneumatic remote control system for a battery of soot-blowers comprises for the control of each soot-blower a valve assembly including a main piston valve 14 which can be pre-set under manual control, a primary valve 11 and a secondary valve 12 both operated by the sootblower, and a motor control valve 13. When the soot-blower is at rest the valve 11 remains closed and the valve 12 is held open. Presetting of the valve 14 causes the blower-driving air motor 10 to be started whereupon the valve 12 is closed and the valve 11 is opened temporarily so as to pass compressed air to the valve 14 which is thereby returned to its initial position and passes air to the closed valve 12. At the end of its cycle of operations the soot-blower opens the valve 12 which passes air to the valve 13 to stop the motor 10 and supplies air to the main piston 14A of the next soot-blower. As shown in Fig. 1, the battery consists of two soot-blowers compressed air being supplied to the motors 10, 10A through pipes 7, 7A and to the control system through pipes 8, 8A, 9. A starter hand valve 16 when held open passes air from the pipe 9 via a filter 18, lubricator 19 and pipe 17 to the valve 14 to pre-set the latter and to a time-lag device 20, 21, 22 which controls the opening of a piston valve 23 for the passage of air there-through from the pipe 17 to the preset valve 14 whence the air passes to the valve 13 which is displaced and supplies air from the pipe 7 to the motor 10. When the second soot-blower stops air from the valve 12A is passed back through piping 33 to the valve 23 which is thus returned to its initial position, a time-lag device being incorporated to the piping 33 to allow the valve 13A to reach its motorstopping position before the valve 23 is returned to its initial position. Knobs 15, 15A associated with the valves 14, 14A indicate, when projected therefrom, that the soot-blowers are in operation. Each soot-blower is provided with an auxiliary manually-operated valve 40 and an associated shuttle valve 41 which, in case a soot-blower fails to operate, allows the latter to be isolated without affecting the operation of the other soot-blowers. The control system may also be hydraulically operated. The valves 11, 12, Figs. 2 and 4, are operated by cam humps 51, 53 mounted on discs 50, 52 provided on a shaft 54 rotatable step-by-step by a non-rotatable nut 71 which reciprocates along a reversible rotary screw 72 in unison with the cleaning fluid ejector forming part of the soot-blower and connected to a shaft 73 which is driven through gearing and clutch mechanism by a shaft 62 rotated by the motor 10. Specification 771,614 is referred to.

Title: New pyrimidine derivatives
Inventor: VASEY CHARLES HENRY
IPC: A61K31/00
Filed: 1952-05-09
Abstract: The invention comprises hexahydropyrimidine-4,6-dione derivatives of the formula <FORM:0734512/IV (b)/1> wherein X and Y are hydrogen, halogen or methyl, and Z is halogen or methyl, R is an alkyl or alkenyl radical of not more than 3 carbon atoms and R1 is hydrogen or an alkyl radical of not more than 4 carbon atoms.  They may be prepared (1) by reacting a malondiamide <FORM:0734512/IV (b)/2> with a compound HCOA where A is NH2 or OH, or with a substance or mixture of substances which yields HCOA in the reaction.  Instead of the malondiamide, there may be used, for example, N-methylol or N-formyl derivatives of the malondiamide; (2) when R stands only for alkyl, by reduction of compounds of the formula <FORM:0734512/IV (b)/3> wherein A is hydrogen or the group -BQ, wherein B stands for oxygen or sulphur and Q stands for hydrogen or an alkyl radical; (3) when at least one X, Y and Z is halogen in the meta position, by mono-nitration of <FORM:0734512/IV (b)/4> followed by replacement of the nitro group by a halogen atom, e.g. via the amino-group.  In the examples: (1) a -(p-chlorophenyl)-a -ethylmalondiamide is heated with formamide to give 5-(p-chlorophenyl)-5-ethyl hexahydropyrimidine-4,6-dione. The following hexahydropyrimidine-4,6-diones are similarly prepared: 5-(p-fluorophenyl) - 5 - ethyl -, 5 - (m - chlorophenyl) - 5 - ethyl -, 5 - (p - and m - bromophenyl) - 5 - ethyl-, 5-(p-chlorophenyl)-5-methyl- and 5-allyl-, 5 - (p - chlorophenyl) - 1 - methyl - 5 - ethyl-, 5 - (41 - chloro - 31 - methylphenyl) - 5 - ethyl-, 5 - (31 - chloro - 41 - methylphenyl) - 5 - ethyl-, 5 - (31,41 - dichlorophenyl) - 5 - ethyl - and 5 - (31,51 - dichlorophenyl) - 5 - ethyl-.  (2) As in example (1) using, instead of formamide, a mixture of dimethylformamide and aqueous formic acid; (3) 5-p-tolyl-5-ethyl-2-thiobarbituric acid is reduced by refluxing with Raney nickel in ethanol to give 5-p-tolyl-5-ethylhexahydropyrimidine - 4,6 - dione.  The 5-m-tolyl-5-ethyl- and 5-p-tolyl-1-methyl-5-ethyl-derivatives are similarly prepared.  (4) The product of example 1 is prepared by heating 2-methoxy-5 - (p - chlorophenyl) - 5 - ethyl hexahydropyrimidine-4,6-dione with formamide.  (5) The same compound is prepared by reducing the starting material of example 4 with Zn and HCl in methanol.  (6) 5-Phenyl-5-ethylhexahydropyrimidine-4,6-dione is nitrated to give the 5 - (m - nitrophenyl) derivative and this is reduced to the 5-(m-aminophenyl) derivative.  By Sandmeyer's reaction, the 5-(m-chlorophenyl) derivative is obtained.  Using as starting material the 5-p-tolyl-derivative, there is obtained 5-(31-chloro-41-methyl phenyl)-5-ethyl hexahydropyrimidine-4,6-dione. Specification 734,511 is referred to.
