缩聚烷基苯合成润滑油的结构分析及机理探讨

Structure analysis and mechanism exploration of the synthetic lubricant condension－ polyalkylbenzene

缩聚烷基苯合成油系由烷基苯与二氯甲烷在无水三氯化铝的催化下进行付－克烷基化反应而得到的。利用傅立叶变换红外光谱仪、色－质联用仪等分析手段对其结构进行了测定和分析。并对其反应机理进行了探索，推断出合理的结构式和反应历程。

Infrared spectrometry and Chromatograph－ mass spectrometer coupling were used to presume the structure of the synthetic lubricant, which was prepared by the reaction of alkylbenzene and methylene dichloride with Lewis acid as a catalyst. Meanwhile, the reaction mechanism was explored preliminarily. Its reasonable constitutional formula and reaction mechanism were infered.
