Organic synthesis, for example, at a temperature of 180 ℃ ~ 200 ℃ and mercury salts (such as HgCl2) as catalyst under the conditions of addition reaction of acetylene with hydrogen chloride to produce vinyl chloride, and then under the action of sulfuric acid initiator, polymerization PVC. Dyeing industry, for example, pickling bleached cotton, mercerized cotton treated residual alkali neutralization, should use hydrochloric acid. In the printing process, some dye does not dissolve in water, treated with hydrochloric acid required to make a soluble hydrochloride, to apply. As the essential raw material of high quality factory nitrate and nitrate sulfuric acid, nitric acid is used for extracting a series of nitrate fertilizer, such as ammonium nitrate, potassium nitrate, etc; also used for extracting nitrates or nitro-containing explosives. Because both nitric acid oxidation and acid, nitric acid is also used to refined metal: the first impure metal is oxidized to nitrate, eliminate impurities and then restored. Nitric acid passivation without continuing to make iron corrosion. Also available nitrogen system, aqua regia, nitrates, nitroglycerine, nitrocellulose, nitrobenzene, picric acid, etc. The glycerol release and concentrated nitric acid, concentrated sulfuric acid efficiently, will generate nitroglycerine. It is a colorless or yellow transparent oily liquid, is a very unstable substance, have been hit the decomposition will occur, resulting in high temperatures, while generating large amounts of gas. Sudden expansion of the gas volume, resulting in a violent explosion. Therefore, a high explosive nitroglycerin. With more than a nitrification is 2,4,6-trinitrotoluene military explosives (TNT). It is composed of toluene with concentrated nitric acid and concentrated sulfuric acid reaction, is an acid yellow flakes professional management, with the explosive power of a large, drug stability, low moisture absorption, etc., used to make bombs, grenades, mines and torpedoes explosives, blasting, etc. can also be used in mining operations.
