Synthesis of Butyraldehyde Glycol Acetal by using TiSiW₁₂O₄₀/TiO₂ as Catalyst

Butyraldehyde glycol acetal was synthesized from butyraldehyde and glycol in the presence of TiSiW₁₂O₄₀TiO₂. The factors influencing the yield of product and the optimum reaction condition were discussed. The optimum condition is the molar ratio of butyraldehyde to glycol is 1:1.5, the quantity of catalyst is equal to 0.5% in mass fraction, and the reaction time is 1.0 h. TiSiW₁₂O₄₀/TiO₂ is an excellent catalyst to synthesize butyraldehyde glycol acetal and the yield can be up to 81.9%.
