Anhydrous aluminum trichloride is an important inorganic chemical substance with a wide range of uses, mainly including the following aspects:

1. Used as a catalyst. Anhydrous aluminum trichloride is a strong acidic Lewis acid, which can be used as a catalyst in organic chemical reactions, such as aromatization reaction, olefin addition reaction, etc.

2. Used as a refining agent. Anhydrous aluminum trichloride can react with metal oxides or hydroxides to form volatile metal chlorides, thereby realizing metal refining.

3. Used as metal surface treatment agent. Anhydrous aluminum trichloride can remove the oxide film on the metal surface, thereby improving the adhesion and corrosion resistance of the metal surface.

4. For synthetic materials. Anhydrous aluminum trichloride can react with organic compounds to form organometallic compounds with specific structures and properties, which are used to synthesize polymer materials, coatings, etc.

5. Used in the preparation of inorganic compounds. Anhydrous aluminum trichloride can react with hydroxide to form inorganic compounds with specific structures and properties, such as metal oxides, hydrogen                     Aluminum chloride - Risk and Safety

Aluminum chloride - Nature

colorless transparent hexagonal plate-like crystals. Industrial products containing iron, free chlorine, free aluminum and other impurities were light yellow, yellow or light gray, strong hydrochloric acid odor. d 2. 44. Melting point of 190~194 deg C, heat about 183 deg C sublimation. Soluble in water, while releasing a lot of heat. Soluble in ethanol, ether, carbon tetrachloride and other organic solvents, insoluble in benzene. Complexes can be formed with many inorganic and organic compounds. Anhydrous Aluminum Chloride has a strong water absorption, water or water vapor reaction heat and produce toxic corrosive gases. Corrosive to many metals, especially in the presence of moist air.

Aluminum chloride - Preparation Method

The aluminum ingot is heated and subjected to chlorine gas for chlorination reaction, and the generated aluminum chloride is sublimated and collected to obtain a finished product. Or a certain particle size of industrial alumina and petroleum coke mixed evenly, into the air for roasting, aluminum oxide powder. Then chlorine gas and oxygen gas were introduced into the aluminum-oxygen powder to conduct the chlorination reaction. The product was pre-cooled, purified and collected to obtain aluminum chloride. It can also be prepared by heating and melting metallic aluminum and then introducing anhydrous hydrogen chloride.

Aluminum chloride - Safety

rat oral LDso:3730mg/kg. It has a stimulating effect on the skin and mucous membranes. When the human body contact anhydrous aluminum chloride, and contact with water at the same time, can burn the skin. Inhalation of high concentrations can cause bronchitis and bronchial asthma. Store in a cool, ventilated warehouse. The packaging must be sealed and free from moisture. Keep away from fire and heat source. Should be stored separately from flammable, combustible, alkali, wet items, etc. Not mixed for storage and transportation.
