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

The effects of PW/SiO2 activation temperature on MPA (p-methoxyacetophenone) synthesis from toluene and acetic anhydride were carefully studied, and catalysts were carefully characterized by BET and XRD. The charactrerized results displayed that the interaction between PW and SiO2 promoted 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 when activation temperature increased to 300 °C, and the appearance of PW12O38.5 over PW/SiO2 resulted in MPA yield decline.
