Appiliations
Hydrogen chloride is used to remove the remaining fibers from cotton seeds after the cotton wool has been separated and before the seed is stored for resowing next season and also to separate cotton from wood.
-1-iydrOgen chloride is used in the manufacture of inorganic chloride's. Hydrogen chloride is used as the chlorine donor in excimer lasers.
Hydrogen chloride is used to promote and regenerate catalysts in the petrochemical industry, and to add viscosity to oils.
Hydrogen chloride is used for hydrochlorinations, e.g.: production of methyl chloride and
oxichlorinations, e.g.: production of vinyl chloride. It is also used to produce sulfuric chlorohydrin, synthetic rubbers, etc.
Hydrogen chloride is used as a thermal etchant to remove material from unmasked areas and to prepare vvafer surfaces for epitaxial deposition.
High purity hydrogen chloride gas is widely used in the electronics industry. It is a chlorine carrier produced by high temperature cracking. It is used in the following applications:
scouring furnaces (quartz chambers)
- dissolved in water as aqueous cleaning agent to prepare metal surfaces for electro plating
selective etching of windows in electronic microcircuits
carrier for non-volatile elements in the form of gaseous chloride. Hydrogen chloride is used in .pharmaceutical synthesis.
Hydrogen chloride is also used for production of hard metals.

Source
Hydrogen chloride is normally prepared in commercial quantities by the direct combination of chlorine and hydrogen. This is achieved by "burning" chlorine in an atmosphere of hydrogen. Most of the hydrogen chloride produced in this may is normally dissolved directly in water to produce hydrochloric acid, but some companies collect the anhydrous hydrogen chloride.
