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 ZnCl2, ZnBr2, CuCl2, CuBr2 and NiCl2 doped in FAP indicate that the best results were obtained with ZnCl2/FAP and ZnBr2/FAP. A high selectivity of monoalkyl compounds was observed in all cases. (C) 2003 Elsevier Science B.V. All rights reserved.
