| Abstract: | Butyraldehyde 1,2-propanediol acetal was synthesized from butyraldehyde and 1,2-propanediol in the presence of H6P2W18O62/SiO2. The factors influencing the synthesis were discussed and the best conditions were found out. The optimum conditions are： molar ratio of butyraldehyde to 1,2-propanediol is 1： 1. 3,the quality of catalyst is equal to 1. 0% of feed stocks,the dried cyclohexane is 6mL,and the reaction time is 60 min. H6P2W18O62/SiO2is an excellent catalyst for synthesizing butyraldehyde 1,2-propanediol acetal and its yield can be up to 92. 3%. |
