Abstract: The invention relates to a method for simultaneous preparation of 6-aminocapronitrile and hexamethylene diamine from adipodinitrile, comprising the following steps: a) hydrogenating adipodinitrile in the presence of a catalyst containing an element of the eight subgroup as catalytically active component to obtain a mixture containing 6-aminocapronitrile, hexamethylene diamine, adipodinitrile and high boilers; b) separating by distillation hexamethylene diamine from the mixture containing 6-aminocapronitrile, hexamethylene diamine, adipodinitrile and high boilers and c1) separating by distillation 6-aminocapronitrile and subsequently d1) separating by distillation adipodinitrile or c2) simultaneously separating by distillation 6-aminocapronitrile and adipodinitrile into separate fractions. The method is characterized in that the temperature of the bottom in steps d1) or c2) is below 185 DEG C.

Abstract: Continuously operated process for the intermediate isolation of the oxirane formed by reaction of a hydroperoxide with an organic compound in the oxirane synthesis, wherein the product mixture formed in the synthesis is fractionated in a dividing wall column to give a low-boiling fraction, an intermediate-boiling fraction and a high-boiling fraction and the oxirane is taken off in the intermediate-boiling fraction at the side offtake and the hydroperoxide is taken off in the high-boiling fraction at the bottom of the column.

Abstract: The invention relates to a method for separating pentenenitrile isomers having a relative volatility alpha in the region 1.0 - 1.3 in a pressure range of 1 - 500 kPa by means of separation. According to said method, the distillation is carried out in the presence of a liquid diluent which forms azeotropes with the pentenenitrile isomers in the same pressure conditions, whose relative volatility alpha is higher than the pentenenitrile isomers which are to be separated.
