摘　　要：以精制菜子油为基础油,考察了几种硫化脂肪添加剂和磷系添加剂对其生物降解性能的影响。试验结果表明,菜子油中加入添加剂后会对其生物降解性能产生影响。添加剂的种类不同,对菜子油的生物降解性能的影响也不相同。所添加的几种添加剂都不同程度地降低了菜子油的生物降解性能,但降幅不大,其生物降解率仍在95%以上。硫、磷系极压抗磨添加剂配伍对菜子油生物降解性能有一定的影响。其中RC2317与P120配伍对菜子油的生物降解性影响不大,而RC2526和RC2540与P120配伍,则使菜子油的生物降解率下降很大。The effect of several sulfureted fatty and phosphorous type additives on the biodegradation of refined rapeseed oil was investigated. The result shows that the biodegradation of rapeseed oil maintains above 95% when adding sulfureted fatty and phosphorous type additives, so the additives have less influence on the biodegradation of rapeseed oil. The compound additives of sulfureted fatty and phosphorous type additives can affect the biodegradation of rapeseed oil to some extent. The compound additives of RC2317 and P120 have less influence on the biodegradation of rapeseed oil, but the compound additives of RC2526 and P120, RC2540 and P120 reduced the biodegradation of rapeseed oil greatly.
