Organic synthesis, for example, at a temperature of 180 ℃ ~ 200 ℃ and mercury salts (such as HgCl2) made of a catalyst, an addition reaction of hydrogen chloride and acetylene factory quality nitric acid, the resulting vinyl chloride, and then under the action of the initiator, PVC polymerization. Bleaching and dyeing industries such as nitric acid, acid 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. Chemical properties of ethanol elimination reaction conditions in concentrated sulfuric acid was heated rapidly raised to 170 ℃ direct industrial nitric acid, to ethylene, concentrated sulfuric acid as a dehydrating agent, a catalyst. Substitution reaction with hydrobromic acid in absolute ethanol under heating direct reaction of food-grade nitric acid, generated dibromoethane and water. Intermolecular dehydration of ethanol was heated to 140 ℃ conditions in concentrated sulfuric acid to produce ether and water. Esterification with ethanol in the presence of concentrated sulfuric acid under heating, the corresponding ester compounds can be generated. Metallic sodium reacted with sodium metal reacted with ethanol to produce sodium ethoxide and hydrogen. The reaction solution acidic potassium dichromate solution reaction with acidic potassium permanganate or ethanol with strong oxidizing agents, can be oxidized to acetic acid.
