描述

Aluminium chloride, or aluminium trichloride, chemically AlCl3, is a compound of chlorine and aluminum. Aluminum chloride melting point, boiling point is very low, and will be sublimated, ionic covalent compounds. The molten aluminum chloride is not conductive, unlike most salts containing halogen ions (such as sodium chloride). ALCL3 adopts the structure of "YCL3", which is the most densely stacked layered structure of al3+ cubic, while al3+ in AlBr3 occupies the adjacent tetrahedron gap of the most densely stacked frame of br−. When melting, the ALCL3 generates volatile two-al2cl6, contains two three-center four electron chloride bridge bonds, and at higher temperature Al2cl6 two-body is dissociated to generate planar triangular AlCl3, similar to the BF3 structure. Aluminum chloride is commonly used in Lewis acid. In the chemical industry, it is often a catalyst for the FU-G reaction. It is also used in hydrocarbon polymerization and isomerization reactions. Aluminum can also produce an aluminum chloride (AlCl), but the compound is unstable and can only occur in gaseous form. Industrially, it is processed by bauxite and is produced by an exothermic reaction between aluminum and chlorine.
