Abstract: Dodecatungstophosphoric acid was synthesized and used as catalyst for oxidation of benzaldehyde to benzoic acid with aqueous hydrogen peroxide. The effect of various catalytic reaction parameters including time, temperatures, and the amount of catalyst on the yield of benzoic acid was investigated in details. The results indicated that the as-prepared sample was in the keggin-type structure and the optimal parameters under the reaction conditions were as follows: 0.5 g of catalyst, reacted at 80 C for 5 h.

Abstract: W-SBA-15 mesoporous material was synthesized by using a one-step co-condensation sol-gel process and characterized by various methods. The results showed that the prepared W-SBA-15 sample retained the typical mesoporous structure of SBA-15 and exhibited good catalytic performance for the green synthesis of adipic acid under organic solvent-free conditions.
