Zinc chloride is one of the important products in the inorganic salt industry, and its application range is extremely wide. Zinc chloride is easily soluble in water and is the most soluble in solid salts (25 ° C, 432 g / 100 g) due to its solubility in water to form the acid H [ZnCl 2 (OH)]. Soluble in methanol, ethanol, glycerin, acetone, ether, insoluble in liquid ammonia. It is highly deliquescent and can absorb moisture from the air and deliquesce. It has the characteristics of dissolving metal oxides and cellulose. Molten zinc chloride has good electrical conductivity. There is a thick white smoke formation when it is hot. Zinc chloride is corrosive and toxic.
Although there are still some problems in the industrial production of domestic zinc chloride, with the continuous development of industrial production and the deepening of research and exploration, the industrial production of zinc chloride will have a broader prospect.
The inorganic industry acts as an activator for the production of activated carbon, making activated carbon a porous material and increasing its surface area. Also used in the manufacture of anti-solvent foam fire extinguishing fluids and raw materials for the production of zinc cyanide. The organic industry is used as a solvent for polyacrylonitrile, an organic synthetic contact agent, a dehydrating agent. Condensing agent, deodorant. Special surfactants and catalysts for the production of vanillin, chloramphenicol, indomethacin, and cation exchange resins. The petroleum industry is used as a scavenger. The dye industry is used as a stabilizer for the coloring salt of ice dyes, and also for the production of reactive dyes and cationic dyes. The rubber industry is used as an auxiliary material for the vulcanization accelerator zPC. The printing and dyeing industry is used as a mordant, a mercerizing agent and a weighting agent. The electroplating industry is used as a zinc ion additive for ammonium salt galvanizing. The pigment industry is used as a raw material for white pigments. The metallurgical industry is used to produce aluminum alloys and to treat metal surfaces. Used as a rust remover during welding.  Coal preparation plants are often used for floating and sinking experiments.
It is used as a dehydrating agent, a condensing agent for the organic synthesis industry, and a catalyst for producing vanillin, rabbit ear aldehyde, anti-inflammatory analgesic drug, and cation exchange resin. Can be used as a solvent for polyacrylonitrile. Dyeing and weaving industry is used as mordant, mercerizing agent and sizing agent. The textile industry is used as a raw material for the production of sliver barrels, shuttles and other materials (co-solvent for cotton fibers) to increase the adhesion of the fibers.
