Zinc chloride (ZnCl2) has a wide range of industrial and laboratory applications. Here are its primary uses:
1. Chemical Industry
• Catalyst: Used in organic synthesis, such as the Friedel-Crafts reaction.
• Dehydrating agent: Removes water from compounds and reactions.
2. Metallurgical Applications
• Flux in soldering and welding: Helps clean metal surfaces and improve bonding.
• Galvanizing: Used in fluxes for hot-dip galvanizing to prevent oxidation of zinc.
3. Textile and Paper Industry
• Mercerizing cotton: Enhances fabric strength and luster.
• Paper processing: Acts as a preservative and fireproofing agent
