Aluminum chloride, alias anhydrous aluminum chloride, aluminum trichloride, chemical formula AlCl 🥰, molecular weight 133.34, CAS No. 7446-70-0, melting point 194 ℃, boiling point 178 ℃ (sublimation), water-soluble and soluble, density 2.44 g/cm ³.

The appearance of aluminum chloride is colorless and transparent crystal or white and slightly light yellow crystalline powder, with a strong smell of hydrochloric acid. Industrial products are light yellow, yellow-green or reddish-brown due to impurities such as iron and free chlorine. Easily soluble in water, alcohol, chloroform, carbon tetrachloride, slightly soluble in benzene. Molten aluminum chloride is not easy to conduct electricity, unlike most salts containing halogen ions (such as sodium chloride). The aqueous solution of aluminum chloride is completely dissociated and is a good conductor.

Aluminum chloride sublimates at 178 ° C, and its vapor is an associated bimolecular. Aluminum chloride easily absorbs water and partially hydrolyzes to release hydrogen chloride to form an acid mist. Easily soluble in water and strongly hydrolyzed, the solution is acidic. Also soluble in ethanol and ether, while releasing a lot of heat.

Main uses of aluminum chloride:

Aluminum chloride is widely used in organic chemistry, as a catalyst and detergent for organic synthesis, and is used in medicine, pesticides, dyes, fragrances, plastics, lubricants and other industries

1. Used as analytical reagent, preservative, mordant

2. Used as a catalyst for organic synthesis, such as petroleum cracking, synthetic dyes, synthetic rubber, synthetic detergents, medicine, fragrances, etc.

3. It is used for the manufacture of pesticides, organoaluminum compounds, catalysts for phthalocyanine organic pigments, and catalysts for the manufacture of ethylbenzene.

4. It is also used in metal smelting and lubricating oil synthesis.

5. Food-grade products are used as anti-discoloration agents such as leavening agents, sake and flocculants for pectin.

6. Organic synthesis catalysts, strong dehydrating agents, acid catalysts, catalysts for making artificial rubber, plastics, lubricants, etc., metallurgy, petroleum cracking, etc.
