摘要
光安定性指被测样品在贮存加工过程中在光氧化下逐渐变质的性质,能够反映光的稳定性,用于衡量润滑油基础油加氢精制深度。综述了润滑油基础油光安定性的影响因素与其作用机理,通过对影响光安定性因素(含硫化合物、含氮化合物、重芳烃以及部分饱和多环芳烃)的分析和基础油光氧化机理的讨论,建议优化分离技术,深入表征结构,合理优化生产工艺,为生产高品质润滑油基础油提供指导依据。
Light stability is defined as the character of gradual deterioration of sample due to photo-oxidization during storage and processing.It can reflect the stability of photo-oxidation and is also used to measure the depth of hydrofining of base oil.In this paper,influence factors and chemical mechanism of light stability of lube base oil were summarized.Through the analysis of the factors(including nitrogen and sulfur compounds,heavy aromatics and some polycyclic aromatic hydrocarbons saturation)affecting the light stability and the discussion of the photooxidation mechanism of base oil,it was suggested that the separation technology should be optimized,the structure should be further characterized,the production process should be reasonably optimized.The paper can provide a guide for the production of high-quality lube base oil.
