摘　　要：采用气相色谱-质谱法分析邻苯二甲酸二异辛酯的加氢反应产物。邻苯二甲酸二异辛酯加氢反应的多种产物在HP-5MS毛细管柱上分离,用质谱检测。通过对相应质谱图的解析,鉴定出10种主要反应产物,推测了主要产物环己烷1,2-二甲酸二(2-乙基)己酯的质谱断裂机理,并提出了邻苯二甲酸二异辛酯加氢反应的各种副反应。GC-MS was used for the analysis of hydrogenation reaction products of Di-（ 2-ethylhexyl） phthalate. The reaction products were separated on a HP-5MS capillary column and detected by MS. Ten compounds were identified by analyzing the mass spectra. The fragmentation mechanism of diisooctyl 1,2-cyclohexanedicarboxylate was postulated,and possible side reactions of the hydrogenation process of di-（ 2-ethylhexyl） phthalate were proposed.
