Catalytic Synthesis of N-Butyl Methacrylate with H₄SiW₆Mo₆O₄₀/SiO₂

Abstract:

A novel environmental friendly catalyst, H₄SiW₆Mo₆O₄₀/SiO₂was synthesized by a sol-gel technique, and characterized by FT-IR and XRD. Catalytic application of the catalyst for synthesis of n-butyl methacrylate was investigated. The variation of different reaction parameters were studied by orthogonal design. Under optimized conditions, that is, molar ratio of methacrylic acid to n-butanol is 1:1.7, catalyst dosage is 0.75 %, volume of cyclohexane is 12 mL and the reaction time is 2.5 h, the yield of n-butyl methacrylate reaches 85.3%. The results reveal that the H₄SiW₆Mo₆O₄₀/SiO₂O2 catalysis is an execellent catalyst for synthesis of n-butyl methacrylate. Introduction
