PROCESS FOR PREPARING IMINODIACETONITRILE AND ALKALI METAL IMINODIACETATES

摘要

Iminodiacetonitrile is prepared by forming an aqueous mixture of hexamethylenetetramine, HCN, and glycolonitrile and passing the mixture through a tubular reactor at about 100 DEG -200 DEG C to form iminodiacetonitrile which is recovered. Alternatively the iminodiacetonitrile exit the tubular reactor is fed into an alkali metal hydroxide solution and hydrolyzed to alkali metal iminodiacetate.
