Welcome to inquire! Contact: Mr Tsang. Organic synthesis, for example, at a temperature of 180 ℃ ~ 200 ℃ and mercury salts (such as HgCl2) as catalyst under the conditions of the addition reaction of hydrogen chloride and acetylene analytically pure toluene, the resulting vinyl chloride, and then under the action of an initiator xylene AR, PVC polymerization. Dyeing industry, for example, pickling bleached cotton, mercerized cotton treated residual alkali and toluene in analytical shelf life, should use hydrochloric acid. In the printing process, the dye is insoluble in water and some isopropyl analytical grade toluene, hydrochloric acid treatment required to make a soluble hydrochloride, to apply. Thionyl chloride pale yellow to red, fuming liquid with a strong smell. Miscible in benzene, chloroform, carbon tetrachloride and other organic solvents. Water hydrolysis, thermal decomposition. Mainly used to produce acyl chloride, also used in the production of pesticides, pharmaceuticals, dyes and the like. With sulfur trioxide and sulfur dichloride reaction.
