摘要： There is provided a process for the direct preparation of fatty acid nitriles andglycerol from glycerides, in particular from natural fats and oils is described in which theglycerides in the liquid phase with a stream of ammonia of at least 200 I / kg of glycerideand hour at temperatures of 220 to 300 ° C are treated as catalysts in the presence oflead, zinc, cadmium, tin, titanium, zirconium, chromium, antimony, manganese, iron, nickelor cobalt salts of carboxylic acids or sulfonic acids, and the product mixture leaving aphase separation is subjected to give a Fettsäurenitrilphase and a glycerol / water phaseis formed. The Fettsäurenitrilphase is advantageously subjected to a post-treatment inthe presence of ammonia and the above-mentioned catalysts to convert formed as anintermediate fatty acid and fatty acid amide in completely nitrile. The crude glycerol canbe purified by known methods. Fatty acid nitriles are known intermediates for thepreparation of primary amines and of quaternary ammonium compounds which are inturn used in particular as a textile and flotation. Glycerin is mainly used in the cosmetics,food industry, manufacture of explosives, as a solvent and for many other purposes.
