ABSTRACT:
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.
