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。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 stability 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 mineral oil.2,6-di-tert-butyl-cresol(T501)antioxidant improves the oxidation stability of oil containing T309.
