| 1. Aluminum chloride is mainly used in the Friedel-gram reaction, such as benzene and phosgene as raw materials to prepare anthraquinone, used in dyeing and finishing industry. In a generalized Friedel-gram reaction, the reaction of acyl chloride or halogenated alkanes with aromatic substances is as follows: right: 2. The main products of benzene and its derivatives are para-isomers when the above reactions take place. In contrast, alkylation involves more problems than acylation. In either case, aluminium chloride and other raw materials and gauges must be moderately dry, and a small amount of water will facilitate the reaction. Since aluminum chloride can coordinate with the reaction product, the amount of aluminum chloride used in the Fourier reaction must be the same as the reactant, not the "catalytic amount". Aluminum chloride after the reaction is very difficult to recover, will produce a large amount of corrosive waste. To meet the requirements of green chemistry, chemists began to use yttrium fluoride or dysprosium fluoride to replace aluminum chloride and reduce pollution. Aluminum chloride is also used to add aldehydes to benzene rings, such as carbon monoxide, hydrogen chloride, aluminum chloride and cuprous chloride. 3. Aluminum chloride is widely used in organic chemistry. It can catalyze Ene reactions such as the addition of 3-butene-2-one (methyl vinyl ketone) and carvone: 4.AlCl3 is also commonly used in hydrocarbon polymerization and isomerization reactions. Important examples include the production of ethylbenzene in industry. Ethylbenzene can be further used in the preparation of styrene, polystyrene and dodecyl benzene as cleaning agent. In the presence of aromatics, the mixture of aluminum chloride and aluminum can be used to synthesize bis (aromatic) metal complexes. For example, diphenyl chromium is synthesized from specific metal halide via Fischer-Hafner. Low concentrations of basic aluminum chloride are often a component of antiperspirants, while hyperhidrosis patients have higher conce |
