Paragraph 0039-0045; 0048, (2020/05/08)
The invention discloses a preparation method of alkyl cyclohexylbromobenzene. The method comprises the following steps: performing a synthesis reaction by adopting one of alkyl cyclohexylbenzene, alkyl dicyclohexylbenzene and biphenyl as a raw material, adopting bromine as a bromine source and adopting an oxidant as a catalyst; washing a synthetic product with water until neutrality to obtain a crude product organic phase; then adding a solvent into the crude product organic phase; heating to a boiling state and refluxing; and finally cooling and performing filtration to obtain a product. Themethod has characteristics of low cost, high yield, no waste gas and no solid waste generation, environmental protection, and is suitable for promotion and use.
