    • This invention relates to the production of aminoacetonitriles, and more specifically to an integrated process wherein a crude, unpurified reactor product stream from a hydrogen cyanide reactor together with a formaldehyde stream, optionally, a crude, unpurified reactor product stream from a formaldehyde process reactor are fed directly to a reactive absorber with an additional nitrogen source and scrubbed with a controlled pH aqueous solution to produce aminoacetonitriles in high yields. This process eliminates intermediate recovery and purification processes associated with conventional hydrogen cyanide and formaldehyde production processes by integrating the recovery and reaction processes into a reactive absorber.

    • 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.degree. to 70.degree. 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.
