Enhanced Selectivity

A variety of solid acid catalysts especially 12-Tungstophosphoricacid (DTP) supported on silica has been reported for the acylation of anisole, veratrole and toluene. However, the activity of this catalyst is susceptible to coke formation or poor activity. This paper reports the novelties of steam treated SiO2-DTP core-shell nanoparticles, which exhibits tremendous stability, high activity and enhanced selectivity in the liquid-phase acylation of anisole, veratrole and toluene as compared to conventional DTP supported on silica.
