| Abstract: | Diethyl maleate was synthesized from maleic anhydride and anhydrous ethanol in the presence of ionic liquid ［TEA-PS］HSO4. The influential factors for the synthesis and reusability of the catalyst were investigated. Diethyl maleate yield of 99% was obtained under the following condition: n(maleic anhydride)∶n(ethanol)＝1∶4, dosage of the ionic liquid＝20%(wt) of maleic anhydride, cyclohexane as water carrier, 115 ℃, reflux and water segregation for 4 h. |

| Keywords: | ionic liquid maleic anhydride esterification catalytic chemistry |
