Abstract: 1,156,158. Hydroxy alkane- and alkenenitriles. BADISCHE ANILIN- & SODAFABRIK A.G. 16 Nov., 1966 [17 Nov., 1965], No. 51327/66. Heading C2C. Nitriles of hydroxyalkane- and hydroxyalkene-carboxylic acids, in which the hydroxy group is separated from the nitrile group by at least 6 carbons, are obtained by heating the corresponding hydroxyalkane- or hydroxyalkene-carboxylic acids, the ammonium salts or the amides thereof in the presence of at least 2 moles of ammonia per mole of acid or at least one mole of ammonia per mole of the ammonium salt or amide of the said acid to a temperature of 250-400‹ C. in the absence of dehydration catalysts at a pressure of 50-150 atmospheres. The ammonia is preferably used in an amount of 10-30 moles per mole of acid, ammonium salt or amide and water or steam may be added to the reaction mixture. In examples, 7-hydroxy-enanthic acid and ricinoleic acid are converted to the corresponding nitriles.
