Hydrochloric acid in organic synthesis areas: for example, at a temperature of 180 ℃ ~ 200 ℃ and mercury salts (e.g. HgCl2) as catalyst under conditions of addition reaction of acetylene with hydrogen chloride to produce vinyl chloride, again in the role of initiator under , polymerization of polyvinyl chloride. Dyeing industry, for example, pickling cotton bleached, mercerized cotton treated residual alkali neutralization, should be treated with hydrochloric acid. In the printing process, some dye insoluble in water, treated with hydrochloric acid required to make a soluble hydrochloride, to apply. Zhengzhou Longda Chemical Products Co., Ltd. was founded in 2003, is a professional sales: sodium hydroxide (caustic soda, liquid, flake, solid), sodium hypochlorite, hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid, ammonia, oxalic acid, bleaching powder, foam flower base, phosphate solution and chemical reagents wholesale benzene, hydrochloric acid, retail, distribution purchase.

Irritating odor. Because of concentrated hydrochloric acid is volatile, volatile hydrogen chloride gas and air role in the formation of hydrochloric acid in water vapor droplets, you will see the mist. Then operation of hydrochloric acid in life should pay attention to? Closed operation, pay attention to ventilation. Operating as mechanization and automation. The operator must go through specialized training concentrated hydrochloric acid, and strictly abide by the rules. Proposed operators wear self-absorption filter respirators (full cover), wear rubber acid suit, wearing rubber gloves acid. Away from flammable and combustible materials. To prevent vapor leakage into the workplace air. Avoid contact with alkalis, amines, alkali metals. When moving to light light unloading, prevent damage to packaging and containers. Equipped with spill response equipment. Empty containers may be harmful residues.
