1Polyaniline Supported 12-Tungstosilicic Acid as the Catalyst for Acetals and Ketals Synthesis显示文摘A novel environmental friendly catalyst, H4SiW12O40/PAn was prepared and identified by FT-IR, XRD and TG/DTA. The optimal synthetic protocol was a PAn to H4SiW12O40 mass ratio of 1∶1, a 20 mL of methanol and a reaction time of 2 h at reflux. It was used in catalytic synthesis of ten important ketals and acetals with a high catalytic activity. With an aldehyde/ketone to glycol molar ratio of 1∶1.5 and a 1 wt% catalyst loading, the yields of ketals and acetals could reach 60.0%-93.8 % after 1 h.杨永金 PHILIPPE G Merle 2009Journal of Wuhan University of Technology(Materials Science)2009,24,3:1
