    Abstract: Purification of hydrocyanic acid such as obtained from ammoxidation by reacting the crude product containing aliphatic and/or isocyclic unsaturated hydrocarbons and/or heterocyclic compounds with a hydrohalic acid or an oxyacid of sulfur or phosphorus, preferably in concentrated form, and thereafter separating the reaction products from the hydrocyanic acid, such as by distillation or adsorption, and recovering substantially pure hydrocyanic acid.
