Abstract

1342045 Nitrilotriacetonitrile MONSANTO CO 20 Jan 1972 [21 Jan 1971] 2700/72 Heading C2C Nitrilotriacetonitrile is produced by reacting together hydrocyanic acid, formaldehyde and a nitrogen source in an acidic liquid medium containing less than 5 equivalents of acid per litre, using the stoichiometric amounts (Œ2% by weight) of CH 2 O and HCN required to react with the nitrogen source, controlling the amount of liquid present in the final reaction mixture at 50-65% by weight, based on the total weight thereof, and maintaining the temperature of the final reaction mixture at 75- 95‹ C. Preferred nitrogen sources are hexamethylenetetramine, NH 3 , a soluble ammonium salt and an aminoacetonitrile intermediate.
