Read： 1129 Time：11months ago Source：Transform the World with Simplicity

Ferric chloride is a kind of chemical raw material with unique properties and wide application. This article will detail the properties and uses of ferric chloride.

1. properties of ferric trichloride

1. physical properties

of ferric trichloride is a dark brown solid with a high melting point (about 306 ℃) and boiling point (about 315 ℃). It is easily soluble in water to form a yellow solution with strong hygroscopicity. When exposed to the air, it will absorb water and deliquesce.

2. chemical properties

ferric chloride is a strong oxidant with high chemical activity. It can react with many metals, non-metals and compounds to generate the corresponding chlorides or oxides. In addition, ferric chloride is acidic and can react with alkali to form the corresponding salt and water.

2. the use of ferric trichloride

1. water purification agent

ferric trichloride as a water purification agent, has a wide range of applications in the field of water treatment. It can coagulate and precipitate with suspended solids and colloidal substances in the water, thereby effectively removing impurities in the water and improving water quality.

2. Catalyst

Ferric chloride as a catalyst plays an important role in many organic synthesis reactions. It can promote the progress of the reaction and improve the selectivity and yield of the product.

3.

of printing and dyeing auxiliaries In the printing and dyeing industry, ferric trichloride is often used as a mordant to combine with dyes to improve the color fastness and dyeing effect of dyes. In addition, it can also be used as a fixing agent to improve the water resistance and washability of the fabric.

4. Electronics Industry

In the electronics industry, ferric chloride can be used to prepare printed circuit boards to form circuits by etching copper foil. At the same time, it can also be used as a cleaning agent for electronic components to remove surface oxides and oil stains.

5. pharmaceutical intermediates

ferric chloride can be used as pharmaceutical intermediates for the preparation of some antibacterial drugs, antitumor drugs and other drugs. In addition, it can also be used to prepare some vitamins and nutritional supplements.

In short, ferric chloride, as an important raw material for chemical production, has been widely used in the fields of water purification agent, catalyst, printing and dyeing auxiliaries, electronic industry and pharmaceutical intermediates. Understanding and mastering the properties and uses of ferric chloride is of great significance for improving the production efficiency and product quality of chemical products.
