| Abstract: | 2 - Methyl - 2 - ethyl acetoacetate - 1,3 - dioxolane was synthesized by the reaction of acetyla- cetic ester with glycol with Is/PAn as the catalyst, and the effect of Is/PAn on the catalytic activity of ketal re- action as well as the effect of molar ratio of materials, catalyst usage and reaction time on product yield were studied. According to the results, I2/PAn is a good catalyst for synthesizing 2 - methyl - 2 - ethyl acetoacetate -1,3 -dioxolane. The optimum reaction conditions were identified, i.e. n （acetylacetic ester） ：n （glycol） = 1 ： 1.6, percentage of catalyst amount in total mass of reaction materials： 0.6%, water carrying agent： cyclohexane, reaction time ： 45 min. The yield of 2 - methyl - 2 - ethyl acetoacetate - 1,3 - dioxolane can reach 86.2% at above conditions. |
