Abstract
Procedure for preparing concentrated chorhydric acid. Wash hydrogen chloride was obtained by reaction of sulfuric acid with an alkaline chloride, such as sodium or potassic chloride, cooling the resultant gas at temperature comprising ambient temperature and 100 c. Washing with chorhydric acid which has a concentration of saturation and containing 1 to 5 per 100 in the weight of an alkaline sulphate, all of it at an ambient temperature and 100 c, where the temperature of the chorhydric acid is comprised amongst the environment and 50 c.
