| Abstract: | Ketals of ethyl acetoacetate withethandiol and 1,2-propylene glycol were synthesized by dealuminated ultrastable Y-zeolitecatalysts, the yield was 80% for ethandiol and 92% for 1,2-propylene glycol. The effectsof the composite of catalysts and reaction time on the reaction were investigated. It wasfound that the adsorption of products is faster than ethyl acetoacetate. The reactionmechanisms were discussed. |
