以金属粉末 C-1为催化剂（用量为酸醇总质量的0.5％），以二甲苯为携水剂，在季戊四醇、辛二酸与油酸的物质的量比为2∶1∶3、缩聚反应时间和反应温度为2 h 和（160±2）℃、酯化反应时间和反应温度为3 h 和（185±2）℃的条件下，按两步法制备了复酯 P，其酸值≤10 mgKOH·g－1，酯化率≥95％。通过红外光谱、凝胶渗透色谱对复酯 P进行了表征，并对其摩擦学性能进行了评价。结果表明，复酯 P 的摩擦学性能良好，以复酯 P 为主体制备的水基润滑剂具有良好的极压抗磨性。

Using metal powder C-1 as catalyst,dimethylbenzene as water-carrying agent,the complex ester P was prepared by two-step method under conditions as follows:the molar ratio of pentaerythrotol(PE),suberic acid and oleic acid was 2∶1∶3,the dosage of catalyst was 0.5% of total mass of PE and suberic acid,condensa-tion time was 2 h,condensation temperature was (160±2)℃,esterification time was 3 h,esterification tempera-ture was (185±2)℃.The acid value was less than 10 mgKOH·g-1 and esterification rate was greater than 95%.The complex ester P was characterized by FTIR and GPC,and its tribological performance was evaluated. Results showed that,complex ester P had better tribological performance,water-based lubricant using complex ester P as main component had better extreme-pressure anti-wear properties.
