A series of WO3 supported on TiO2 catalysts were prepared by impregnation method with varying WO3 content. The prepared catalysts were characterized by FT-IR, Laser Raman, X-ray diffraction, BET surface area and temperature programmed desorption of NH3. X-ray diffraction and Laser Raman spectroscopic results suggest that WO3 was highly dispersed on titania up to 15 wt%. Acidity of the catalyst depended up on WO3 loading on titania and calcination temperature. The catalyst with 15 % WO3 content calcined at 500 degrees C exhibited high surface area and high acidity. Activity of the catalysts was evaluated for the synthesis of glycerol carbonate from glycerol and urea. The catalytic activity results showed that 15 % WO3 supported on TiO2 exhibited about 73 % glycerol conversion with near 100 % selectivity for glycerol carbonate. The influence of support on glycerol conversion was also studied and activities for different supports were in the order of TiO2 > SiO2 > MoO3 > Nb2O5 > ZrO2 > Al2O3. Different reaction parameters were also studied and optimum conditions were established. The catalyst is reusable without considerable loss in activity.
