| Abstract: | The chloroapatite(ClAP) supported metal halides catalysts were prepared by the hydrothermal method using ClAP as the support.The catalysts were characterized by the techniques such as IR and XRD.Friedel-Crafts benzylation reactions of aromatic compounds with benzyl chlorides,benzyl bromides and benzyl alcohols were investigated.The experiments indicated that the best results were obtained with ClAP supported ZnBr2.Furthermore,the catalyst could be easily recovered by simple method and reused for at least 5 ... |
