多元醇酯类冷冻机用基础油的合成及其性能

摘要

采用新型催化酯化反应工艺合成了新戊基多元醇脂肪酸酯,酯化反应转化率高达98.5%以上;FTIR分析表明,酯的羟基吸收峰消失,表明酯化反应具有高的羟基转化程度.采用该合成工艺制备了冷冻机用基础油,结果表明,基础油性能达到国外同类产品的性能指标.%Neopentyl polyol-based fatty acid ester was synthesized with a novel catalytic esterification process. The conversion rate of esterification reached more than 98.5%. The disappearance of hydroxyl absorption peak of ester showed that the esterification has high hydroxyl conversion rate. Basestock of refrigerator oil was prepared via above-mentioned process. The test result indicated that the basestock performance can reach the level of the same type of imported samples.
