Chemical Description

  • Zinc Chloride dissolves metal oxides and cellulose, and its molten form exhibits good electrical conductivity.
  • In the organic synthesis industry, it serves as a dehydrating agent and catalyst, and in dyeing and weaving, it acts as a mordant, sizing agent, and weighting agent.
  • It can purify petroleum and activate carbon, while also serving as a fireproof substance for clothing and fabric odor cleaner.
  • Zinc Chloride attacks metal oxides to generate MZnOCl2, functioning as a metal flux.
  • In water treatment, it slows the corrosion rate of other metals.
  • In agriculture, Zinc Chloride is essential for crop growth in Zinc-deficient soil and is used as a chelating agent in Zinc products.
  • Welders use Zinc Chloride-containing flux to aid in welding and clean metal surfaces, enhancing soldering fastness.
  • In dry batteries, Zinc Chloride paste controls electrons, provides electrical power, and offers moisture-proof and anti-corrosion effects.
  • Its low production cost makes it suitable for intermittent power supply equipment like flashing barricade lights, navigation equipment, and electronic watches.
  • In the organic synthesis industry, Zinc Chloride acts as a Lewis acid catalyst, facilitating reactions such as Friedel-Crafts acylation and alkylation.
  • It is used as a dehydrating agent and catalyst, enabling the synthesis of pharmaceuticals, fragrances, and fine chemicals.
  • In the dyeing and weaving industry, Zinc Chloride serves as a mordant, sizing agent, weighting agent, dye fixative, and color modifier.
