| 摘 要： | 研究了用固体超强酸SO42-/Fe2O3-TiO2为催化剂,由马来酸和正丁醇反应合成马来酸二丁酯的最佳工艺条件。结果表明,当n(酸):n(醇)=1:3.5,催化剂用量为马来酸质量的5%,带水剂环己烷为15ml(马来酸用量为0.1mol时),反应时间为3h,酯的产率可达96%。该工艺产率高,反应时间短,无腐蚀无污染。

| Abstract: | The optimum technological conditions were studied on the synthesis of Dibutyl maleate by the reaction of maleic acid and n-butanol with SO_4~2-/ Fe_2O_3-TiO_2 as catalyst.The results showed that the yield was over 96% when molar ratio of n-butanol and maleic acid was 4.0:1,reaction time of reflux was 3.0h mass of catalyst was 5% of maleic acid.This process has many advantages such as higher yield,simple procedure,shorter reaction time,non-corrosive,non-pollution,etc. |
