摘　　要：3-(3,5-二叔丁基-4-羟基苯基)丙酰亚磷酸季戊四醇酯是一种抗氧化性和热稳定性优良的抗氧剂,在聚烯烃中得到广泛的应用。以3-(3,5-二叔丁基-4-羟基苯基)丙酸甲酯(简称3,5-甲酯)、亚磷酸三苯酯、季戊四醇为原料,碳酸钾为催化剂合成了3-(3,5-二叔丁基-4-羟基苯基)丙酰亚磷酸季戊四醇酯。考查了催化剂、反应温度、反应时间及物料配比等因素的影响,确定了反应的最佳条件。在此条件下,收率在95％以上。并通过元素分析、红外光谱分析、核磁氢谱对产品进行组成结构表征。3-(3,5-di-butyl-4-hydroxyphenyl) propionyl pentaerythritol phosphite is an excellent antioxidant. It was widely used in polyolefins. In this paper, it was prepared with pentaerythritol (Ⅰ), triphenyl phosphite (Ⅱ) and methyl-3-(3, 5-di-tert-butyl-4-hydroxyphenyl)-propionate (Ⅲ) (3,5-methylester for short) as raw materials, and K2CO3 as the catalyst. The influence of catalyst, reaction temperature, reaction time and molar ratio of raw materials on product yield were studied. The optimum reaction conditions were determined and developed. On this condition, product yield can be up to 95%. The composition and structure of product was characterized by element analysis, IR, and HNMR.
