Abstract: 1,086,231. Endothermic reactions. SOCIETE GENERA LE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM), April 20, 1965 [April 20, 1964], No. 16623/65. Heading B1X. The heat required for an endothermic reaction to take place between a first fluid, e.g. fuel, introduced in pulses through conduit 1 to a reaction vessel 2 and a second fluid, e.g. water vapour, injected also in pulses at 4 into alternate pulse cuts of the first fluid is obtained from an exothermic reaction which takes place between the first fluid and a third fluid, e.g. air, also injected in pulses at 3 into the other set of alternate pulse cuts of the first fluid. The reactions are initiated in vessel 2 and continue in a conduit 5 which has a large wall surface through which heat is exchanged. After completion of the reactions the fluid is cooled in heat exchangers 6 and 7, which are used for heating the air and for producing the water vapour, and then passed to a washing tower 8 before separated at 9 by valves into the distinct pulse cuts 10 and 11 of the fluid.

Abstract: A mixture of monochloro-e -caprolactams, mainly b - and g -chloro, is obtained by irradiating with light a mixture of monochlorocyclohexane and a nitrosation agent at -20 DEG to 50 DEG C., and subjecting the resulting monochlorocyclohexanone oxime hydrochloride to a Beckmann rearrangement at 90-150 DEG C., directly or after neutralization to free oxime. Specified nitrosation agents are NOCl, NO + Cl2, NO + NO2 + HCl, NOCl + HCl, and NO + Cl2 + HCl. Some caprolactam is also obtained in the examples, and one example also prepares cyclohexanone oxime hydrochloride from cyclohexane.

Abstract: Lactams are prepared by the reaction of a cycloalkanecarboxylic acid or an alkyl derivative thereof with nitrosyl hydrogen pyrosulphate. The reaction may be carried out in an inert solvent, e.g. in aliphatic, cycloaliphatic, chlorinated aliphatic hydrocarbon or nitroparaffin. The acid may be one having 4-12 carbon atoms in the ring. Examples are given for the preparation of caprolactam, capryllactam, valerolactam and lauryllactam. The process is operated at a temperature between 30 DEG and 150 DEG C. The lactam is separated by extracting the unreacted acid from the mixture by solvent extraction; neutralizing the remaining aqueous solution with an alkaline material, and extracting the lactam with a solvent, e.g. benzene, chloroform or methylene dichloride.

Abstract: Caprolactam is prepared by reacting a compound containing a cyclohexyl group having a tertiary carbon atom in the ring with a nitrosylating agent capable of producing NO+ ions in the reaction medium, in the presence of sulphuric acid and optionally SO3 also, the reaction being carried out in the presence of carbon tetrachloride as a heat-transfer solvent. The reactants may be those disclosed in Specifications 904,302, 904,413 and 912,034. Specification 924,098 also is referred to.
