摘　　要：以邻苯二甲酸二甲酯和二乙二醇单丁醚为原料、有机锡为催化剂,通过酯交换法在无溶剂的条件下催化合成邻苯二甲酸二（二乙二醇单丁醚）酯,通过正交实验考察了催化剂用量、反应温度、反应时间及物料配比等因素对反应的影响,并通过元素分析、红外光谱分析对产品进行了结构表征。结果表明,当邻苯二甲酸二甲酯用量为0.1 mol、邻苯二甲酸二甲酯与二乙二醇单丁醚的摩尔比为1∶2.20、催化剂有机锡用量为1.5 g、反应时间为4.0 h、反应温度为180~190℃时,邻苯二甲酸二（二乙二醇单丁醚）酯的产率在88%以上,折光率（25℃）为1.4892~1.4896。Transesterification of methyl phthalate with diethylene glycol monobutyl ether catalyzed by organic tins was investigated.The effects of catalyst amount,reaction time,reaction temperature,molar ratio of methyl phthalate to diethylene glycol monobutyl ether on the reaction were studied.The experimental result showed that when the molar ratio of methyl phthalate to diethylene glycol monobutyl ether was 1∶2.20,catalyst amount was 1.5 g,reaction time was 4.0 h,reaction temperature was 180～190℃,the yield of bi（diethylene glycol monobutyl ether） phthalate could be up to 88%,refractive index of the product was 1.4892~1.4896 at 25℃.The structure of the product was characterized by elemental analysis and IR analysis.
