zinc dichloride

Zinc chloride is the name of chemical compounds with the formula ZnCl2 and its hydrates. Zinc chlorides, of which nine crystalline forms are known, are colorless or white, and are highly soluble in water. ZnCl2 itself is hygroscopic and even deliquescent. Samples should therefore be protected from sources of moisture, including the water vapor present in ambient air. Zinc chloride finds wide application in textile processing, metallurgical fluxes, and chemical synthesis. No mineral with this chemical composition is known aside from the very rare mineral simonkolleite, Zn5(OH)8Cl2·H2O.

Application

As an activator in the production of activated carbon, inorganic industry makes activated carbon become porous and increases its surface area. It is also used as a raw material for the manufacture of anti-dissolving foam extinguishing fluid. Organic industry as a solvent for polyacrylonitrile, organic synthesis of contact agents, dehydrating agent. Shrinkage mixture, deodorant. Special surface activators and catalysts used in the production of vanillin, aldehyde-free, anti-inflammatory drugs and cationic exchange resins. The petroleum industry is used as a purifier. The dye industry is used as a stabilizer for color developing salt of ice dye, and also for the production of reactive dyes and cationic dyes. Rubber industry as a vulcanization accelerator ZPC auxiliary material. Printing and dyeing industry as mordant, mercerizing agent, weight - adding agent. Zinc ion additive for ammonium salt zinc plating industry. The pigment industry USES white pigments as raw materials. The metallurgical industry is used to produce aluminium alloys and to treat metal surfaces.
