| Abstract: | Isobutyl amyl acetate is synthetized from isobutyric acid and alcohol wit solid superacid Fe2 O3-TiO2-Nd2O3/S2O8^2-
as catalyst. The effects of the ratio of esterification by different reaction conditions are studied in this papaer. The result shows that the best reaction conditions： molar ratio of alcohol and acid being 1： 1.4（ weight of isobutyric acid is 0.1 mol） ,weight of cat-alyst is 1.4 g, the reaction temperature is 100℃and reaction time is 4h, the ratio of esterification is 78.8%. The catalyst can be used repeatedly with little cor- rosion to equipments. |
