Paper Title:
Support Effects of PW/SiO2 on Friedel-Crafts Acylation of Toluene with Acetic Anhydride
  Abstract

Support effects of PW/SiO2 on MPA (p-methoxyacetophenone) synthesis from toluene and acetic anhydride were carefully studied, and catalysts were carefully characterized by BET, XRD and NH3-TPD. The charactrerized results displayed that the interaction between PW and SiO2 prevented the loss of acidic protons from PW to form the weak acid PW12O38.5 over PW/SiO2. The weak acid site PW12O38.5 over PW/SiO2 came into being only in case of much more PW being loaded onto SiO2, and the appearance of PW12O38.5 over PW/SiO2 resulted in MPA yield decline.
