Read： 1285 Time：13months ago Source：Transform the World with Simplicity

Copper hydroxide is an important raw material for chemical production and has a wide range of applications. This article will detail the properties and uses of copper hydroxide.

1. the nature of copper hydroxide

copper hydroxide is a blue solid powder, insoluble in water, but soluble in acid, alkali and ammonium salt solution. Copper hydroxide is stable in air, but decomposes into copper oxide and water at high temperatures. Copper hydroxide is weakly alkaline and can react with acid to form the corresponding copper salt and water.

2. Use of Copper Hydroxide

1. Catalyst

Copper hydroxide can be used as a catalyst to promote many organic reactions. For example, copper hydroxide can catalyze the oxidation of aldehydes and ketones to the corresponding carboxylic acids. In addition, copper hydroxide can also catalyze the epoxidation of olefins.

2. pigment

copper hydroxide is a blue pigment, commonly used in paints, coatings, plastics and printing and dyeing industries. Because of its good heat resistance, light resistance and corrosion resistance, it is widely used in high temperature, high humidity and corrosive environment.

3. preservative

copper hydroxide has antibacterial effect, commonly used as a preservative added to food, cosmetics and pharmaceutical products. It can inhibit the growth of bacteria and extend the shelf life of the product.

4. Ceramic Industry

Copper hydroxide is used as one of the raw materials for glazes in the ceramic industry, which can give ceramic products a unique blue appearance. At the same time, copper hydroxide can also improve the wear resistance and chemical corrosion resistance of the glaze.

In short, copper hydroxide, as an important raw material for the production of chemical products, has been widely used in the fields of catalyst, pigment, preservative and ceramic industry.
