Abstract: Described is a process for the production and recovery of hydrogen cyanide, which includes recovering hydrogen from a crude hydrogen cyanide product. The process includes forming a crude hydrogen cyanide product and separating the crude hydrogen cyanide product to form an off-gas stream and a hydrogen cyanide product stream. The off-gas stream is further separated to recover hydrogen. The hydrogen cyanide product stream is further processed to recover hydrogen cyanide.
