摘　　要：The Flory-Huggins interaction parameter(χ1,2∞) and solubility parameter(δ2) and its hydrogen bonding sensing component(δh) were determined using inverse gas chromatography(IGC).These parameters were successfully used in the probes of chemical changes that occur during the oxidation of naphthenic and paraffinic base oils in a GC column.Changes in χ1,2∞ values reflect the different types of intermolecular interactions(dispersive,polar,hydrogen bonding) of the given lubricating base oil during oxidation.The obtained results showed that δh component of solubility parameter is the most important parameter for probing the oxidative-chemical changes during the oxidation of given lubricating oils. 关键词：反相气相色谱氧化稳定性润滑原油溶解参数计算
