Abstract

A process for the preparation of aminopropionitriles of the general formula I ##STR1## in which R denotes hydrogen or methyl, wherein ammonia is caused to react with an acrylonitrile of the general formula II ##STR2## In which the substituent has the aforementioned meanings, in a molar ratio of from 1:1 to 500:1 over a heterogenic catalyst at temperatures ranging from 40.degree. to 180.degree. C. and pressures ranging from 10 to 350 bar.
