| abstract | 1,190,458. Preparation of amides. BADISCHE ANILIN- & SODA-FABRIK A.G. 8 Sept., 1967 [9 Sept., 1966], No. 41119/67. Heading C2C. Amides or polyamides are prepared by reacting a nitrile with H.COOH at 150-350‹ C. and a superatmospheric pressure at least equal to the vapour pressure at the temperature used of the reactants, the substances formed in the reaction and the solvent, if present. The H.COOH used is preferably more than 80% by weight strength, 98-100% by wt. being desirable. The nitrile and H.COOH may be used in equivalent amounts or the nitrile may be added in excess to act as a solvent. The process is particularly suitable for the preparation of amides from aliphatic, cycloaliphatic, araliphatic or aromatic nitriles and from aliphatic, cycloaliphatic or araliphatic hydroxycarboxylic nitriles. Hydroxycarboxylic nitriles yield polyamides, from which amino acids are obtainable by hydrolysis. In the examples (1) p-chlorobenzonitrile; (2) undecylenonitrile; (3) 3-chlorobenzonitrile, and (4) terephthalonitrile are converted to pchlorobenzamide, undecylenamide, 3-chlorobenzamide and terephthalodiamide respectively; and (5) to (7) isobutyraldehyde-, n-butyralhyde-, and ethylene-cyanohydrins are converted via polyamides to valine, α-amino-valeric acid, and #-alanine respectively. |
