Abstract:
Provided is a method for producing a hydrogen chloride that is capable of efficiently producing a hydrogen chloride with a simple facility. The hydrogen chloride is produced by a method including obtaining chlorine and hydrogen by electrolyzing an inorganic chloride aqueous solution of which a pH is 3 to 5, obtaining a crude hydrogen chloride by reacting the chlorine and the hydrogen obtained in the electrolyzing at 1000° C. to 1500° C. with a use of an excess quantity of the hydrogen with respect to the chlorine in a molar ratio, dehydrating the crude hydrogen chloride obtained in the reacting, and compressing and liquefying the dehydrated crude hydrogen chloride obtained in the dehydrating, and purifying the liquid crude hydrogen chloride by distillation.

Claim (Index 4):
The method for producing a hydrogen chloride according to  claim 2 , wherein the dehydrating comprises absorbing the crude hydrogen chloride obtained in the reacting in water to make a hydrochloric acid, and dehydrating a hydrogen chloride diffused from the hydrochloric acid.
