Zinc chloride technical finds application in various industrial processes due to its versatile properties. Some common applications of zinc chloride technical include:

1. Flux in Soldering: It is widely used as a flux in soldering applications. Zinc chloride technical helps remove oxide layers from metal surfaces, allowing better bonding between the solder and the metal. The flux also promotes the flow of solder and improves the wetting properties on the surfaces being soldered.
2. Galvanizing: Zinc chloride technical is utilized in the galvanizing process, which involves applying a protective zinc coating to steel or iron surfaces. It helps clean and activate the metal surface, ensuring better adhesion of the zinc coating.
3. Catalyst: It serves as a catalyst in various chemical reactions, such as Friedel-Crafts acylation and alkylation reactions. Zinc chloride technical aids in the formation of new chemical bonds and enhances reaction rates.
4. Dehydrating Agent: Due to its hygroscopic properties, zinc chloride is employed as a dehydrating agent in numerous applications. It can remove water from organic compounds, such as alcohols and amines, facilitating reactions that require anhydrous conditions.
5. Wood Preservative: Zinc chloride is used as a wood preservative to protect against fungal decay and insect infestation. It can be applied to timber through pressure treatment methods, extending the lifespan of wooden structures and preventing deterioration.
6. Battery Electrolyte: In certain types of batteries, such as zinc-carbon batteries, zinc chloride serves as an electrolyte. It enables the flow of ions between the battery’s electrodes, facilitating the electrochemical reactions that generate electrical energy.
7. Textile Processing: Zinc chloride finds use in textile processing, particularly in the manufacture of viscose rayon. It acts as a catalyst in the production of cellulose xanthate, an intermediate compound used to produce rayon fibers.

Organic Synthesis: Zinc chloride is employed as a reagent in various organic synthesis reactions, including the preparation of organizing compounds and the conversion of alcohols to alkyl chlorides.
