    Abstract: 1,129,108. #-Dodecadienic lactam. STAMICARBON N.V. 31 March, 1966 [6 April, 1965], No. 14250/66. Heading C2C. #-Dodecadienic lactam is prepared by reacting a cyclododecadiene oxime with HCl and/or an imidochloride or imidochloride hydrochloride in the presence of a polar solvent. Exemplified imidochlorides are benzimidochloride and N-methylformimidochloride and suitable solvents are nitro compounds, halogenated hydrocarbons, e.g. CHCl 3 , and nitriles, e.g. CH 3 CN, C 6 H 5 CN. The dodecadienic lactam formed may be reduced or hydrogenated to form laurolactam, e.g. using hydrogen with a palladium catalyst in methanol solution. Reference has been directed by the Comptroller to Specification 942,815.

    Abstract: o -Laurolactam is prepared by reacting cyclododecanone oxime hydrochloride with hydrogen chloride in the presence of a polar organic solvent. Suitable solvents are nitro compounds of hydrocarbons, e.g. nitromethane, nitropropane, nitrobenzene and nitrocyclohexane, halogenated hydrocarbons, e.g. chlorobenzene, chloroform, trichloro-ethylene and isopropyl chloride and nitriles, e.g. acetonitrile, benzonitrile and adiponitrile. The cyclododecanone oxime hydrochloride may contain more than the equimolecular amount of hydrogen chloride, the reaction being carried out with or without further addition of hydrogen chloride. A catalyst may be used, suitable ones being phosgene and halogenated organic nitrogen compounds. The reaction is preferably carried out at between 30 DEG and 125 DEG C.
