摘要/Abstract

摘要： 以碳酸钾为催化剂，通过酯交换法以2,5-呋喃二甲酸二甲酯（DMF）和正丁醇为原料合成了2,5-呋喃二甲酸正丁酯（DBF），并在控制单因素变量实验的基础上，利用响应面法研究了工艺的反应条件（反应时间、催化剂用量、反应温度）对DBF产率的影响。结果表明，合成DBF的最佳反应条件为：反应温度为90 ℃，催化剂碳酸钾的用量为DMF用量的4 %（质量分数，下同），反应时间为76.05 min时，DBF的平均产率为96.47 %。

Abstract: In this work, dibutylfuran-2,5-dicarboxylate (DBF) was synthesized by a transesterification method using dimethyl furan-2,5-dicarboxylate (DMF) and n-butyl alcohol as raw materials and potassium carbonate as a catalyst. The effects of synthetic conditions including reaction time, catalyst dosage and reaction temperature on the yield of DBF were investigated by a response surface methodology on the basis of singlefactor experiments. The results indicated that the optimum conditions for the synthesis of DBF were obtained at a reaction temperature of 90 ℃, a catalyst content of 4 wt % in DMF and reaction time of 76.05 min, and an average yield of 96.47 wt % was achieved for DBF when being synthesized at such conditions.
