摘要(Abstract)：

白油是锂离子电池湿法聚乙烯(PE)隔膜生产中的造孔剂。针对白油循环使用过程中油品外观发黄、黄色物质未定性等问题，采用傅里叶变换红外光谱技术研究了模拟生产工艺条件下白油、PE、抗氧化剂1010(I1010)的结构变化与耐黄变性能的关系，以及质量比不同的3种物料混合物的结构变化、耐黄变性能与质量比的关系；采用高效液相色谱和高分辨质谱技术对回收油中黄色物质进行了定性分析。结果表明，白油、PE和I1010在工艺过程中均发生氧化反应，变黄物质的产生是三者协同作用的结果，其中PE和I1010为主要诱因；黄色物质为芳香酯类化合物和I1010。本研究为白油循环使用工艺的改进提供参考。
