Industrial Grade Zinc Chloride

Описание

Industrial grade zinc chloride (ZnCl₂) is an inorganic salt with a variety of unique chemical properties:Physical form: Usually a colorless or white crystalline powder, but may appear yellow or brown at high temperatures. Solubility: Easily soluble in water, and releases a lot of heat during dissolution; also soluble in organic solvents such as ethanol, glycerol and acetone. Hydrolysis properties: Hydrolysis occurs in water to produce zinc hydroxide (Zn(OH)₂) and hydrochloric acid (HCl).

This reaction is reversible and varies with the pH value of the solution. Thermal stability: Decomposes under heating conditions to produce metallic zinc and chlorine gas, usually requiring higher temperatures and specific conditions. Reaction with metals: It can react with certain metals to produce metal chlorides and metallic zinc, such as reacting with iron to produce ferrous chloride and metallic zinc. Reaction with acids: Reacts with strong acids (such as sulfuric acid, nitric acid, etc.) to produce corresponding zinc salts and hydrogen chloride gas.

Industrial grade zinc chloride has important applications in many fields due to its wide range of chemical properties:
Catalyst: Lewis acid catalyst used in organic synthesis to promote esterification, alkylation, condensation of alcohols, phenols and aldehydes, and arylation of aromatic compounds. Used in synthetic reactions in the pharmaceutical industry. Industrial grade zinc chloride used as a promoter and catalyst in the rubber industry to improve the vulcanization speed and quality of rubber products.Flux: Flux used in metal welding to remove oxides on the metal surface and improve welding quality, especially widely used in soldering and brazing. Used as an additive in the electroplating industry to improve the quality and uniformity of the electroplating layer.
Preservative: Industrial Grade Zinc Chloride used in wood treatment as a preservative to prevent wood from rotting and insect infestation, and to extend the service life of wood. Used as a preservative in the food and pharmaceutical industries. Used for anti-corrosion and anti-rust treatment, such as battery manufacturing, plastic processing, fire retardant coatings and other fields
Desiccant and dehydrator: Due to its strong water absorption, it is used as a desiccant to keep the environment dry or absorb moisture from the air.

In summary, industrial-grade zinc chloride not only has important research value in the field of chemistry, but also plays a key role in many industrial fields.
