Description

C01C covers the production, purification, and chemical compounds of ammonia and cyanogen, along with their derivatives. This includes synthetic ammonia manufacture, ammonia recovery processes, and the preparation of cyanides, isocyanides, and related nitrogen-containing compounds. The subclass encompasses both industrial synthesis methods and laboratory-scale preparation techniques for ammonia and cyanogen-based products used in fertilizers, chemicals, and pharmaceutical synthesis.
