Solvent free esterification of benzyl alcohol over zirconia, vanadia and ceria supported on hierarchical MFI (Mobil Five) zeolite

  Mithun Nandi

Hierarchical MFI zeolite was prepared by simple and economic alkali treatment from a sample of MFI with Si/Al molar ratio 100 which was synthesized by hydrothermal technique using green protocol. The catalytic activity of zirconia, ceria and vanadia loaded onto hierarchical MFI has been tested for benzylalcohol esterification by acetic acid. A green protocol for the esterification reaction was followed avoiding the use of any solvent. Ceria loaded sample was found to be most suitable catalyst for the reaction providing 76% conversion of alcohol and 100% selectivity for the ester. The kinetics of the reaction was also monitored for each catalyst. The reaction in all the cases follows first order kinetics with maximum rate constant of 5.19 x10-3 s-1 for the ceria supported catalyst
