Friedel-Crafts acylation of anisole catalyzed by green, reusable hydroxyapatite-zinc bromide catalyst

摘要

This study was aimed at the development of a green and reusable catalyst for Friedel-Crafts acylation.Firstly,Hydroxyapatite (HAP) and Hydroxyapatite-zinc bromide (HAP-ZnBr2) have been prepared by the co-precipatation method and hydrothermal method respectively.Their structures were characterized by X-ray Diffraction (XRD),Brunauer-Emmett-Teller (BET) and Infrared Spectroscopy (IR).The catalytic efficiency of HAP-ZnBr2 was examined for Friedel-Crafts acylation of anisole.The results showed that the catalyst was green,high activity,high selectivity and it could be reused at least 5 times without obvious activity loss.
