| titleOfInvention | Method for preparing maleic acid ester by catalyzing maleic anhydride with ionic liquid |
| abstract | The invention discloses a method for preparing maleic acid ester by catalyzing maleic anhydride with ionic liquid, which is characterized by comprising the following steps: mixing ionic liquid with maleic anhydride and fatty alcohol, heating to 80-140 ℃, and reacting for 0.5-4 h to obtain maleic ester, wherein the dosage of the ionic liquid is 0.1-10 mol% of the maleic anhydride, and the molar ratio of the fatty alcohol to the maleic anhydride is 2-12. High value-added chemicals are prepared with fully esterified maleic acid esters as the main product. The method has the advantages of simple process, mild condition, environmental friendliness, high double esterification degree, high activity of the ionic liquid, difficult inactivation and realization of recycling. |
