Abstract

A new environmental friendly catalyst,H4SiW6Mo6O40/SiO2 was prepared by the method of Sol-gel.H4SiW6Mo6O40/SiO2 was used as the catalyst in the synthesis of butanone glycol ketal.The effects of varying the n(Butanone):n(ethylene glycol) ratio,catalyst dosage,cycloheaxne and reaction time on the yield were investigated.The optimal conditions were found to be: n(butanone)∶n(ethylene glycol)=1∶1.4;mass fraction of catalyst to reactants,0.6%;dried cyclohexane,10mL and reaction time,75 min.Under these conditions,the yield of Butanone glycol ketal was 96.77%.
