Abstract

Butanone glycol ketal was synthesis from butanone and ethylene glycol in the presence of SO 4 2- /TiO 2-MoO 3. The factors influencing the synthesis were discussed and the best conditions were found out. The optimum conditions are: molar ratio of butanone to ethylene glycol was 1∶1.25, the quantity of catalyst was equal to 0.5% feed stock, the reaction temperature was 80℃～99℃, and the reaction time was 2.0 h. SO 4 2- /TiO 2-MoO 3 was an excellent catalyst for synthetizing butanone glycol ketal and its yield can reach 92.5%.
