Application
1.Hydrometallurgy
Precipitation for rare metals
2.Organic Synthesis
For example, in the 180 ºC ~ 200 ºC and mercury salts (such as HgCl2) as a catalyst ,under the conditions of hydrogen chloride and acetylene addition reaction, the formation of vinyl chloride, and then under the action of the initiator, polymerization of polyvinyl chloride
3.Bleaching and dyeing industry
For example, after cotton mercerizing , the residual alkali could be washed by hydrochloric acid. In the printing and dyeing process, some dyes do not dissolve in water, hydrochloric acid may change these dyes into soluble hydrochloride salt.
4.Metal cleaning
Steel parts,before electroplating, at first cleaning with caustic soda solution to remove oil, and bathing with hydrochloric acid.Remove all oil and metal oxide on its surface.
5.Food industry
Hydrochloric acid is used to hydrolyze starch to produce starch syrup
6.Production of Inorganic and organic drugs
