    Abstract: Process for the preparation of saturated primary fatty amines by hydrogenation of unsaturated fatty acid nitriles According to the new process, the hydrogenation of unsaturated fatty acid nitriles or mixtures of unsatu- rated and saturated fatty acid nitriles is carried out in the liquid phase in the presence of nickel catalysts or cobalt catalysts. In a first reaction step the fatty acid nitrile, in the presence of ammonia, is treated with hydrogenation hydrogen until all the nitrile groups are hydrogenated to predominantly primary amino groups. After the ammonia content in the reaction mixture obtained from the first step has been adjusted to a value of at most 0.1 mol of ammonia per mole of fatty acid nitrile used, a second reaction step is used to hydrogenate the double bonds present to saturated bonds. The desired primary and saturated fatty amine is obtained in a very high yield and has an iodine number of at most 5.

    Abstract: HOE 87/E 916 J of the disclosure Process for the sulfation of partial esters of aliphatic polyhydric alcohols A process for the sulfation of primary free OH groups of partial esters of aliphatic polyhydric alcohols with SO3 is described. As solvent, use is made of at least one compound which has a boiling point of 40 to 200.degree.C at a pressure of 98 kPa, is liquid under the chosen reaction conditions and, in addition to at least one trivalent nitrogen atom, which is linked exclusively to carbon atoms, contains only carbon, hydrogen and optionally ether oxygen atoms. The sulfated partial esters and also their alkali or alkaline earth salts are obtained with a good color and good yield and without the formation of large quantities of salts which pollute the waste water. They may be used, for example, for detergent base materials, synthetic soaps and flotation agents.

    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.
