Application:
Most hydrogen chloride is used in the production of hydrochloric acid. It is also an important reagent in other industrial chemical transformations, e.g.:
Hydrochlorination of rubber
Production of vinyl and alkyl chlorides

In the semiconductor industry, it is used to both etch semiconductor crystals and to purify silicon viatrichlorosilane (SiHCl3).

It may also be used to treat cotton to delint it, and to separate it from wool.
