Heterogeneous catalysis of Friedel-Crafts alkylation by the fluorapatite alone and doped with metal halides

The fluorapatite (FAP) alone or doped with metal halide have been used as the new heterogeneous catalysts for the alkylation of benzene, toluene and p-xylene. The comparison of the activities of ZnCl 2, ZnBr 2, CuCl 2, CuBr 2 and NiCl 2 doped in FAP indicate that the best results were obtained with...

Description
Summary:The fluorapatite (FAP) alone or doped with metal halide have been used as the new heterogeneous catalysts for the alkylation of benzene, toluene and p-xylene. The comparison of the activities of ZnCl 2, ZnBr 2, CuCl 2, CuBr 2 and NiCl 2 doped in FAP indicate that the best results were obtained with ZnCl 2/FAP and ZnBr 2/FAP. A high selectivity of monoalkyl compounds was observed in all cases.
