Abstract: Cyclododecanone is prepared by allowing at least the equivalent amount of an acid and water to act on cyclododecanone oxime or by allowing at least the equivalent amount of water, or water and an acid, to act on a cyclododecanone oxime hydrohalide, the process being carried out at a temperature above 40 DEG C. The hydrolysis is preferably carried out by refluxing the oxime or oxime salt with an excess of water or aqueous organic or inorganic acid and the ketone may be separated continuously from the reaction mixture in a current of steam. In examples, cyclododecanone is prepared by heating the oxime with 10% HCl and with glacial acetic acid and water and by heating the oxime hydrochloride with water, 10% HCl, 10% H2SO4 and 30% H2SO4.

Abstract: Saturated hydroxy carboxylic acid nitriles and/or unsaturated carboxylic acid nitriles are prepared by reacting a lactone or a C-alkylated lactone with gaseous ammonia in the presence of an acid dehydration catalyst at elevated temperature. The omega-hydroxy carboxylic acid amide may be obtained as by-products. Specified lactones are gamma-butyro-, deltavalero-, epsilon-capro-, zeta-oenantho-, etacaprylo-lactones and their alkyl derivatives. Suitable dehydration catalysts include phosphoric acid, acid phosphates, boron phosphates and sulphuric acid and its acid salts, as such or on carriers.

Abstract: Omega:omega1 - diamino - alkanes of the formula H2N.(CH2)x+1.NH2, where x represents the series of whole numbers from 3 to 13, are prepared by catalytic hydrogenation in the presence of ammonia of a lactim ether of the formula where -OR represents a C1-4 alkoxy group. The reaction may be carried out at elevated temperatures and pressures in the presence of a hydrogenation catalyst. The lactim ethers are prepared by treating the corresponding lactams with a dialkyl sulphate or an alkyl halide. Specification 535,023, [Group IV], is referred to.
