Catalytic Application of H₄SiW₁₂O₄₀/SiO₂ in Synthesis of Acetals and Ketals

Abstract:

A novel catalyst, H₄SiW₁₂O₄₀/SiO₂ was synthesized by a sol-gel technique, and characterized by FT-IR and XRD. Catalytic application of H₄SiW₁₂O₄₀/SiO₂ for synthesis of acetals and ketals were tested. The variation of different reaction parameters, such as mole ratio of aldehyde/ketone to alcohols, catalyst dosage and reaction time on the yield of acetals and ketals were also studied. The results reveal that the H₄SiW₁₂O₄₀/SiO₂ catalysis generally results in good yields of acetals and ketals under mild reaction conditions and the high activity and stability of the catalyst is well retained on recycling.
