Zinc chloride anhydrous -for plating materials, catalysts

Anhydrous zinc chloride (CAS: 7646-85-7) is a significant industrial chemical with a variety of applications, particularly in the fields of electroplating and catalysts. Here are some of its primary uses:

1. Plating Grade: Anhydrous zinc chloride is extensively used in the electroplating industry for coating metals with a layer of zinc. It provides a protective layer that is resistant to corrosion, and it is particularly used for electroplating steel to prevent rusting. The anhydrous form is preferred in plating baths due to its higher purity and solubility, which allows for faster plating rates and better deposit quality.

2. Catalyst Grade: In the chemical industry, anhydrous zinc chloride serves as a catalyst in various organic synthesis reactions. It can be used in the production of chemicals such as pharmaceuticals, dyes, and pigments, where it aids in speeding up the reaction rates and improving the yield of desired products.

3. Metal Processing: It is used in the metal processing industry for the purification of metals and in the production of special alloys. Its ability to selectively bind with certain elements makes it useful in the refining of metals.

4. Textile Industry: In the textile industry, anhydrous zinc chloride is used as a mordant to fix dyes to fabrics, ensuring colorfastness and vibrancy.

5. Pharma and Nutraceuticals: It is used as a dietary supplement in the form of zinc, which is an essential trace element for humans and animals.

6. Laboratory Applications: In laboratories, anhydrous zinc chloride is used in various chemical analyses and as a reagent in scientific research.

7. Corrosion Inhibition: It can be used in formulations to protect metals from corrosion, especially in harsh environments.

8. Batteries: Anhydrous zinc chloride is also used in the production of certain types of batteries, such as zinc-carbon batteries, due to its electrochemical properties.

Given the diverse applications of anhydrous zinc chloride, it is an important chemical with significant industrial value. However, due to its potential toxicity and corrosive nature, it is crucial to handle it with proper safety measures to ensure the well-being of workers and the environment.
