Abstract: Glycerides are reacted with ammonia in an amount of at least 200 liters per kilogram of glyceride per hour, at a temperature of 220 DEG to 300 DEG C., and in the presence of special catalysts. Of the product mixture which is formed and removed from the reaction with the excess ammonia, and which is composed essentially of the components water, the desired glycerol and fatty acid nitrile containing fatty acid and fatty acid amide, the latter component is returned to the reaction during the glyceride reaction. After completion of the glyceride reaction, which is indicated when the product mixture contains virtually no more glycerol, all the fatty acid nitrile containing fatty acid and fatty acid amide is further treated, in an after-reaction with a reduced amount of ammonia and at higher temperature, in order to convert the fatty acid and fatty acid amide impurities into fatty acid nitrile.

Abstract: A process for the preparation of fatty acid esters of short-chain primary and secondary alcohols with 1 to 5 carbon atoms by transesterification of glycerides with the said short-chain alcohols is described. In this process, a stream of the gaseous alcohol is passed through the liquid glyceride at temperatures of at least 210 DEG C. and the product mixture of gylcerol and fatty acid alkyl ester is discharged from the reaction zone with this stream and is then subjected to phase separation.

Abstract: Glycerol and aliphatic nitriles are simultaneously produced by treating liquid glycerides with gaseous ammonia at a rate of at least 200 liters of ammonia per kilogram of glyceride per hour at temperatures of from 220 DEG to 300 DEG C. in the presence of metal salts of carboxylic or sulfonic acids as catalysts and subjecting the product mixture to a phase separation into a nitrile phase and a glycerol/water phase. Preferred starting materials are vegetable and animal fats and oils.
