Product Description Product Description Zinc chlorid is an inorganic compound, composed of zinc and chlorine. It is a white crystalline solid, highly soluble in water, and exhibits strong hygroscopicity (absorbs moisture from air). As a potent Lewis acid, it is widely used in industrial and chemical processes for its reactivity and versatility.Physical and Chemical PropertiesFormula: ZnCl2Molar Mass: 136.315 g/molAppearance: White crystalline solid or colorless solution.Melting Point: ~290°CBoiling Point: ~732°CSolubility: Extremely soluble in water (432 g/100 mL at 25°C), ethanol, and acetone.Hygroscopicity: Forms concentrated aqueous solutions upon exposure to air.Acidity: Strong Lewis acid, catalyzes acid-dependent reactions.Synthesis and ProductionLaboratory PreparationIndustrial Production:Chlorination of zinc-containing materials (e.g., slag or ores).Byproduct of zinc refining processes.ApplicationsMetallurgy:Flux: Removes oxides during soldering, welding, and galvanizing.Electroplating: Key component in zinc electroplating baths.Chemical Synthesis:Catalyst: Facilitates Friedel-Crafts acylations, alkylations, and cyclization reactions.Dehydrating Agent: Used in organic synthesis (e.g., forming acetals).Textile and Wood Processing:Fireproofing: Impregnates fabrics and wood to reduce flammability.Mercerization: Enhances cotton fiber strength and luster.Pharmaceuticals and Personal Care:Antiseptic: Diluted solutions in mouthwashes and wound disinfectants.Deodorant: Inhibits microbial growth in cosmetic products.Miscellaneous Uses:Smoke Grenades: Generates zinc oxide smoke for obscuration.Batteries: Electrolyte in zinc-carbon batteries.Petroleum Industry: Coagulant in oil refining.Biological and Medical RelevanceZinc as a Nutrient: Essential for immune function, enzyme activity, and DNA synthesis.Topical Applications: Low concentrations (0.1-1%) in antiseptics; higher concentrations cause tissue damage.
