Abstract Zirconium (benxyldiethylammoniomethylphosphonate chloride)phosphate Zr(HPO4)2-x (O3PCH2N+Et2 CH2ph-Cl−)x-H2O, (0.25 < x < 0.75, ZBEPC-ZP) were prepared for the first time and characterized by IR andelemental analyses. ZBEPC-ZP catalyzed some typical PTC reactions in L/S/L phases were carried out to give good results. ZBEPC-ZP can be easily separated from the reaction mixture and recovered
