 A process for producing hydrogen cyanide by reacting methane or a gas containing methane as a main component, ammonia and an oxygen-containing gas in the presence of a platinum-containing catalyst, wherein the reaction gases are quenched by using an indirect heat-exchanger, preferably made of a nickel alloy having an iron content of not more than 4.0% by weight, without quenching them directly with water.
