Synthesis of acetals and ketals catalyzed by H4SiW6Mo6O40/SiO2

摘要：

　　Heterogeneous acid catalyst,H4SiW6Mo6O40/SiO2 was synthesized by a sol-gel technique.Catalytic application of the catalyst for synthesis of acetals and ketals were tested.The variation of different reaction parameters on the yield of acetals and ketals were also studied.The yields of acetals and ketals can reach 80.0%~96.9% at the optimized conditions.The high activity and stability of the catalyst is well retained after 4 runs.The results reveal that the H4SiW6Mo6O40/SiO2 catalysis is a novel,effective and reusable catalyst for synthesizing actetals and ketals.
