Title: Study of Catalyzed Synthesis of Ester by Acid Functionalized Dacational Ionic Liqiud
Abstract: In this issue,bis-( 3-methyl-1-imidazole) butylidene double bisulfate( MTEIMHS) was used as a catalyst to synthetize isoamyl isobutyrate and Isoamyl butyrate. The yield of esterification rate under the influence of the reaction conditions was measured. The results showed that under the optimized conditions of isoamyl isobutyrate : n( isoamylol) ∶ n( isobutyric acid) = 1. 2 ∶ 1,catalyst used dosage 2. 0g and 3. 5h,the yield of isoamyl isobutyrate reached 95. 4%. The results showed that under the optimized conditions of Isoamyl butyrate: n( isoamylol) ∶ n( butyric acid) = 1. 6∶ 1,catalyst used dosage 2. 0g and 3h,the yield of isoamyl isobutyrate reached 97. 9%. The reaction mixture was immiscible with MTEIMHS and could be speparated simply by separatory funnel after reaction. The ionic liquid catalyst could be reused for 6 times without noticeable lowering of activity.
