摘要
研究采用高压差示扫描量热法(PDSC)考察了油品研究和生产中常用的抗磨剂硫代磷酸三苯酯(T309)对加氢精制矿物油氧化安定性能的负面影响,结果表明:当T309的质量分数＜0.2％时,其对加氢精制矿物油氧化安定性能的负面影响不会显现出来;当T309的质量分数＞0.2％时,其对加氢精制矿物油氧化安定性能有明显的负面影响;抗氧剂2,6-二叔丁基对甲酚(T501)可以改善含T309油品的氧化安定性能.
Abstract
In this study,the pressurized differential scanning calorimeter(PDSC)is used to investigate the negative effects of triphenyl thiophosphate(T309),an antiwear agent commonly used in oil research and production,on the oxidation stabili-ty of hydrofined mineral oil.The results show that:when T309＜0.2％,its negative effect on the oxidation stability of hydrofined mineral oil is zero;when T309＞0.2％,it has obvious negative effect on the oxidation stability of hydrofined min-eral oil.2,6-di-tert-butyl-cresol(T501)antioxidant improves the oxidation stability of oil containing T309.
