How to safely use hydrochloric acid? Special risks: with some active metal powder reacts hydrochloric acid plant, hydrogen. Cyanide case can produce highly toxic hydrogen cyanide gas. The occurrence and reaction with a base, and release a lot of heat. With strong corrosive. Hazardous combustion products: hydrogen chloride. Fire fighting methods: with an alkaline substance such as sodium bicarbonate, sodium carbonate, slaked lime neutralization. It can also be a lot of water to fight the blaze. Industrial hydrochloric acid, hydrochloric acid English name alias hydrochloric acid, technical formula HCL Molecular Weight 36.46 Physical and chemical properties of pure hydrogen chloride is a colorless gas with a pungent odor. That is hydrochloric acid aqueous solution, colorless pure hydrochloric acid. Industrial mouth due to the presence of iron, chlorine and other impurities Hebei hydrochloric acid manufacturers, slightly yellow. The relative density of 1.155 hydrogen chloride melting point -114.8 degrees Celsius. The boiling point of -84.9 degrees Celsius. Soluble in water, there is a strong corrosive and can corrode metal industrial synthesis of hydrochloric acid manufacturers, animal and plant fiber and human skin have a corrosive effect. Concentrated hydrochloric acid fuming in the air, hitting a white male ammonia vapor cloud. Hydrogen chloride gas was harmful to plants and animals. Hydrochloric acid is a strong inorganic acids hydrochloric acid production factory in Shandong, with metal effect can generate and release chlorine metal chloride; salt and water with a metal oxide effect; starting with a base in the reaction to form a salt and water; and salts can play metathesis reaction to generate a new salt and a new acid. Purpose is to create ammonium chloride, calcium chloride, zinc chloride, copper chloride, basic aluminum chloride, ferric chloride liquid and other raw materials. And pharmaceutical intermediates in the synthesis of dyes, for diazotization amino, nitro group into an amino group, converted to sulfonic acid sodium salt. Also used in the synthesis of polyvinyl chloride, chloroprene rubber, ethyl chloride. Also for the hydrometallurgical (such as decomposition of tungsten ore production of tungsten acid, etc.), metal surface treatment (as copper pickling rust). In the printing industry, for fabric bleach pickling, mercerized after the like. In addition, for the regeneration of ion exchange resins, sugar and leather industry.
