Abstract
Hydrocyanic acid is synthesized from a mixture of gas, or gas and steam mixtures containing carbon, hydrogen, and nitrogen by heating to a high temperature effected in the high-tension arc. The process is characterized by the employment of pressures higher than atmospheric, for example an excess pressure of 1.6-atmospheres.
