Aminonitriles are prepared by reacting a nitrogen compound with formaldehyde and hydrogen cyanide in the presence of an additional acid at a pH below 2 and at from 10 DEG to 70 DEG C., the concentration of the hydrogen cyanide during the reaction being not more than 3 per cent by weight, based on the reaction mixture. The aminoacetonitriles obtained by the novel process are valuable starting materials for the preparation of dyes, fungicides, bactericides, textile assistants, rubber additives, and auxiliaries used in water softening, cosmetics, the photographic industry, the paper industry and the electroplating industry.
