Abstract: Improvement of a process for the preparation of unsaturated nitriles from hydrocyanic acid and esters of unsaturated alcohols and carboxylic acids in the gaseous phase in the presence of carrier catalysts containing copper(II) salts, cobalt salts or mixtures of both salts, by additionally passing hydrogen halide, water or oxygen or oxygen containing gases, in admixture or as single components, over the catalyst either simultaneously with the reactants or alternately one after the other.

Abstract translation: 在含有铜（II）盐，钴盐或两种盐的混合物的载体催化剂存在下，通过另外通过氢气，改进在氢氰酸和不饱和醇和羧酸的酯中制备不饱和腈的方法， 卤化物，水或氧或含氧气体，混合物或作为单一组分，与催化剂同时反应或交替使用。
