Industrial use of hydrochloric acid (a) in the various sectors of the national economy, the use of hydrochloric acid is widely described as follows: (1) for the rare metal hydrometallurgical (2) used in organic synthesis (3) for the dyeing industry (4 ) for metalworking (5) for the food industry (6) Hydrochloride just some examples of the industrial production of organic and inorganic chemicals and drugs used in the production of the above-listed. In fact, the use of hydrochloric acid is still too many. In our daily lives, we sometimes also use it, for example the lack of stomach acid, indigestion, the doctor gave us a certain amount of dilute hydrochloric acid to supplement stomach acid. In chemical experiments and scientific research, use of hydrochloric acid in the place even more. Hydrochloric acid in organic synthesis areas: for example, at a temperature of 180 ℃ ~ 200 ℃ and mercury salts (such as HgCl2) as catalyst under the conditions of hydrogen chloride and acetylene addition reaction, Zhengzhou hydrochloric acid to produce vinyl chloride, and then the initiator Under the action, the polymerization of polyvinyl chloride. Dyeing industry, for example, hydrochloric acid pickling cotton bleached, mercerized cotton treated residual alkali neutralization, hydrochloric acid use, to be used for hydrochloric acid. In the printing process, some dye insoluble in water, treated with hydrochloric acid required to make a soluble hydrochloride, to apply.
