摘要
以3-（3，5-二叔丁基-4-羟基苯基）丙酸甲酯（MPC）和三甘醇为原料，在无溶剂的条件下采用酯交换法合成双[3-（3，5-二叔丁基-4-羟基）苯基]丙酸三甘醇酯。最佳合成条件为：在90℃加人有机锡催化剂，用量为MPC质量的2．3％；反应温度130℃；反应时间3．5h；n（MPC）：n（三甘醇）=2．10：1．00，在此条件下产物收率大于91％，产物熔点106-106．5℃。通过元素分析、红外光谱分析、^1H NMR分析对产物分子结构进行了表征。
Triethylene glycol bis[3-（3,5-di-tert-butyl-4-hydroxyphenyl）]propionate was synthesized by transesterification of methyl-3-（3,5-di-tert-butyl-4-hydroxyphenyl） propionate with triethylene glycol without solvent. The optimum conditions were found as follows. 2.3% organic tin based on MPC as catalyst, adding at 90 ℃, reaction temperature 130 ℃, reaction time 3.5 h, and molar ratio of MPC to triethylene glycol 2.10 ： 1.00. Under these conditions, the yield of the product could reach 91%. The melting point of the product was 106 - 106.5 ℃. The product was characterized by elemental analysis, IR and ^1H NMR.
