ABSTRACT:
Cyanoformamide is prepared when cyanogen is contacted with a catalyst solution containing low molecular aliphatic carboxylic acids, from 0.025 to 1.0 mole/1 of copper-(II)-salts and up to 5% by weight of water. Hydrogen cyanide can be used instead of cyanogen, if the catalyst solution contains nitrate ions in addition.
