Title: Improvements in or relating to the Synthetic Production of Ammonia.
Inventor: MAXTED EDWARD BRADFORD
IPC: C01B3/02
Filed: 1918-04-04
Abstract: A mixture of nitrogen and hydrogen for the production of ammonia, or the hydrogen alone, is purified from carbon monoxide by preliminary passage over a base-metal catalyst, such as nickel or cobalt, at a temperature, such as 350 DEG  C., which is below that required for the production of ammonia but sufficiently high for the production of methane.  The gases are treated while under pressure, which may suitably be that required afterwards for the production of ammonia.
Patent GB-626151-A (GB)
Title: Improvements in or relating to the production of cellular polyethylene
IPC: C08J9/06
Filed: 1947-02-27
Abstract: Cellular polythene is produced by incorporating an organic blowing agent, maintaining the mix at a temperature below the gas-forming temperature during operations prior to blowing, e.g. rolling, calendering, extruding, casting or moulding, subsequently raising the temperature to the gas-forming temperature whilst the mass is under pressure, releasing the pressure at or below a temperature within the softening range of the composition and then allowing the material to expand while it is at, or after reheating to, e.g. in a mould, a temperature within the softening range.  If the decomposition temperature of the blowing agent is above the softening range, the mixture may be heated under pressure, e.g. in a mould, to the decomposition temperature and then cooled to the right consistency before releasing the pressure.  In a modification, after the blowing agent has been decomposed under pressure, e.g. in the barrel of an extrusion machine, the material is allowed to expand simultaneously with release of pressure and is then cooled rapidly.  The blowing agent is a substance which, at or slightly above the melting point of polythene, but below its decomposition temperature, decomposes to form gaseous products and a high boiling substance which plasticizes polythene.  The blowing agent may itself act as a plasticizer. Specified are diazoaminobenzene, diazoaminobenzoic acid, diazobutyric acid dinitrile, benzoyl peroxide, urea, sym-dibenzoyl urea, di-isobutyl urea, diphenyl sulphamide, 3,4-dihydroxyazobenzene, diketo-succinic acid and dithiourethane. Polyisobutylene and liquids exerting a high vapour pressure, such as xylene and alcohol, may be added to the mix.ALSO:Cellular polythene is produced by incorporating an organic blowing agent (see Group IV (a)), maintaining the mix at a temperature below the gas-forming temperature during operations prior to blowing, subsequently raising the temperature to the gas-forming temperature whilst the mass is under pressure, releasing the pressure at or below a temperature within the softening range of the composition and then allowing the material to expand while it is at, or after reheating to, e.g. in a mould, a temperature within the softening range.

Title: Decomposition of metal compounds dissolved in oxygencontaining organic products
IPC: C07C45/50
Filed: 1950-03-14
Abstract: Oxygenated compounds obtained by the action of CO, with or without H2, on organic compounds in the presence of catalysts which produce soluble metal compounds in the final product, are treated to decompose said metal compounds by introducing, at elevated temperature and a pressure of 10-80 atmos., a gas containing H2 and 0.1-50 per cent, preferably 10-50 per cent CO.  Unsaturated hydrocarbons, aldehydes, ketones, alcohols, ethers, acids, halides, amides, sulphides, cyanides, sulphates, sulphonates, and esters such as vinyl esters, as well as compounds having a feeble bond which may be broken under the reaction conditions, e.g. dialkyl formals, acetals containing aromatic or cyclo-aliphatic groups, cyclic acetals such as 1,3-dioxolane, and aliphatic cyclic ethers may be formylated to yield aldehydes, ketones, and acids.  Metal, e.g. iron, nickel or cobalt, carbonyls, and particularly cobalt hydrocarbonyl are suitable catalysts.  The products, produced at a pressure above 100 atms., may be cooled and decompressed to the pressure required for decomposition of metal compounds, part or all of the CO liberated, if desired, being conveyed to the decomposer.  The temperature therein may be up to 250 DEG  C. and is preferably 150-220 DEG  C. pressure is preferably 25-50 atms.  The metal may be deposited on a carrier such as pumice and used as catalyst in a subsequent hydrogenation, for example of aldehydes to alcohols.  In examples: aldehydes obtained by formylation of C6 or 7-C8 alkenes, using cobalt hydrocarbonyl or cobalt on kieselguhr as catalyst are treated with gas mixtures comprising H2 and 41.1 or 22 per cent CO at 25 atmos. and 180-200 DEG C.ALSO:Cobalt-hydrocarbonyl is prepared by saturating with CO a solution in air-free water of cobalt nitrate, potassium hydroxide and cyanate, acidifying with phosphoric acid, passing CO, and leading the discharged gas through a drier and a condenser. Alternatively, gas containing CO and H2 is reacted with a cobalt-containing mass at a pressure of, say, above 100 atmospheres and temperature of, say, 80-130 DEG C.  A liquid such as alkene-containing hydrocarbons may be passed over to dissolve the hydrocarbonyl.
