{{main|Hydrogen cyanide#Production and synthesis}}
The principal process used to manufacture cyanides is the [[Andrussow process]] in which gaseous [[hydrogen cyanide]] is produced from [[methane]] and [[ammonia]] in the presence of [[oxygen]] and a [[platinum]] [[catalyst]].<ref>{{cite journal

Sodium cyanide, the precursor to most cyanides, is produced by treating [[hydrogen cyanide]] with [[sodium hydroxide]]:<ref name=Ullmann />
