What are the uses of zinc chloride?

June 20, 2022

Zinc chloride, also known as zinc chloride powder, CAS No.: 7646-85-7, white powdery solid, molten zinc chloride has good conductivity, is easy to absorb water and deliquescence, and is corrosive. It is recommended to store it in a ventilated place and sealed in a cool and dry environment at 2-8 ° C.

Zinc chloride is one of the important commodities in the inorganic salt industry. It is widely used in printing and dyeing plants and in the production of dye making agents. Zinc chloride is easily soluble in water, ethanol, glycerol and other organic solvents, but insoluble in liquid chlorine, etc.

The main uses of zinc chloride are:

1. inorganic industrial production: zinc chloride can be used to produce insoluble foam extinguishing liquid; It can also be used as raw material for producing zinc cyanide; It can also be used as an activator for the production of activated carbon, so that the activated carbon becomes a porous structure and expands its area.

2. organic industrial production: zinc chloride can be used as an organic solvent for polyacrylonitrile in organic industrial production, an organic contact agent, dehydration agent, condensation agent, deodorizer, special surface activator, and a catalyst for the production of vanillin, imperatoric aldehyde, indomethacin, and cation exchange resin.

3. petroleum industry production: as a purifying agent.

4. industrial production of dye: as a stabilizer for color developing salt of ice dye, it is also used for the production of reactive dyes and cationic dyes.

5. rubber industrial production: as auxiliary material of vulcanization accelerator ZPC.

6. printing and dyeing industrial production: as mordant, mercerizing agent and weight increasing agent. The electroplating process is used as zinc ion additive for ammonia salt zinc plating.

7. pigment industrial production: as raw material of white pigment.

8. metallurgical industry: used to produce aluminum alloy profiles and solve metal surface. Used as rust remover during electric welding. It is common for coal washing plants to conduct sinking and floating experiments.

9. production of organic synthesis industry: it is used as dehydration agent and condensation agent for the production of organic synthesis industry and catalyst for the production of vanillin, rabdosia aldehyde, anti-inflammatory and analgesic drugs and cation exchange resin. It can be used as an organic solvent for polyacrylonitrile.

10. dyeing and weaving industry production: as mordant, mercerizing agent and sizing agent.

11. production of textile industry: as the raw material (the cosolvent of cotton fiber) for the production of cotton sliver barrels, shuttles and other raw materials, it can improve the adhesion of chemical fibers.
