ABSTRACT:
The invention is directed to a process for the production of iminodiacetonitrile by reaction of hexamethylenetetramine with hydrogen cyanide in acidic aqueous mediums. In this process the pH during the reaction which is 5.5 to 7.5 at the beginning is progressively lowered, altogether around 0.5 to 3.5 units and free formaldehyde is present only to a slight extent. Through this and in contrast to the known processes the formation of byproducts is suppressed and iminodiacetonitrile is produced directly in very good yields and sufficiently pure for further use.
