ABSTRACT:
This invention relates to the production of iminodiacetonitrile, and more specifically to an integrated process wherein a crude, unpurified reactor gas stream from a hydrogen cyanide reactor and optionally, a crude, unpurified reactor gas stream from a formaldehyde process reactor are fed directly to a reactive absorber together with additional ammonia and acidified water to produce iminodiacetonitrile in high yields. This process provides improved economics for producing iminodiacetonitrile by eliminating costly intermediate recovery and purification processes associated with conventional hydrogen cyanide and formaldehyde production processes.
