Abstract: The invention concerns a process for simultaneously preparing 6-aminocapronitrile and hexamethylene diamine proceeding from adipodinitrile. The process is characterized in that: (1) adipodinitrile is partially hydrogenated in the presence of a catalyst in order to obtain a mixture containing 6-aminocapronitrile, hexamethylene diamine and adipodinitrile; (2) 6-aminocapronitrile and hexamethylene diamine are separated from the mixture; (3) between 0.01 and 10 wt %, relative to adipodinitrile, of an acid or an acidic ion exchanger is added to the part substantially containing adipodinitrile, and the adipodinitrile is separated from the mixture; and (4) the adipodinitrile is returned to step (1).

Abstract: A process for the preparation of an epoxide in the presence of a zeolite catalyst, in which (i) an alkene is reacted with a hydroperoxide in the presence of the catalyst to obtain the epoxide, at least one alkali metal salt being fed into the reaction in at least one precursor stream, wherein (ii) during the reaction the addition of the at least one alkali metal salt is stopped and hydroperoxide and alkene are still fed into the reaction.

Abstract: The invention relates to a method for simultaneous production of 6-aminocapronitrile and hexamethylenediamine from adipodinitrile, comprising the following steps: a) hydrogenating adipodinitrile in the presence of a catalyst containing an element of the VIII subgroup thereby obtaining a mixture containing 6-aminocapronitrile, hexamethylenediamine, adipodinitrile and high boilers; b) distillative separation of hexamethylenediamine from the mixture containing 6-aminocapronitrile, hexamethylenediamine, adipodinitrile and high boilers or c1) distillative separating 6-aminocapronitrile and subsequently d1) distillative separation of adipodinitrile or c2) simultaneous distillative separation of 6-aminocapronitrile and adipodinitrile into separate fractions. The invention is characterized in that temperatures in the bottoms of the column in steps d1) or c2) are under 185 DEG C. The adipodinitrile thus obtained contains less impurities than for instance 1-amino-2-cyanocyclopentenes.
