ABSTRACT:
Disclosed is a process for preparing malononitrile which comprises reacting diazoacetonitrile with hydrogen cyanide in the presence of a copper compound in a solvent. The diazoacetonitrile may be formed in a reaction mixture by reacting aminoacetonitrile with nitrous acid in a solvent, which is then subjected to the further reaction as such without isolating it from the reaction mixture.
