Abstract: of the disclosure Process for the continuous preparation of polyhydroxyfatty amides from N-alkylpolyhydroxyamines and alkyl esters of fatty acids In the process according to the invention, an N-alkyl-polyhydroxyamine, for example N-methylglucamine, is reacted with an alkyl ester of a fatty acid and in the presence of a basic catalyst. The reaction is carried out continuously in at least two, preferably in two or three, stirred tanks arranged in a cascade, under defined conditions in each stirred tank. Polyhydroxy-fatty amides, for example N-methyl fatty glucamides, are obtained continuously in high yield and purity with the process according to the invention.

Abstract: HOE 86/F 921 of the disclosure Glycerides are reacted with ammonia in an amount of at least 200 liters per kilogram of glyceride per hour, at a temperature of 220 to 300.degree.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: HOE 90/F 917 Process for the preparation of saturated primary fatty amines by hydrogenation of the corresponding unsaturated primary fatty mines In the novel process, the hydrogenation of the double bonds in an unsaturated primary fatty amine is achieved by reaction of the unsaturated primary fatty amine with hydrogen at a temperature of 80 to 160.degree.C and a pressure of 1 to 40 bar in the liquid phase and in the presence of 0.1 to 10% by weight of a nickel catalyst or cobalt catalyst. If the fatty amine to be hydrogenated contains ammonia, the latter is substantially removed before the hydrogenation process.
