一、前言r 羽扇烷是一种 A、E 环为五元环,B、C、D环为六元环、A 及 E 环都带有异丙烷基的环烷烃化合物。它存在于一些石油和生油岩中。早在六十年代,许多学者就用色谱仪和质谱仪研究过羽扇烷类化合物,A.I.Burlingame、I.R.Hil-1s 和 E.V.Whitehead(1966)等分别在绿河页岩的抽提物中和尼日利亚石油中鉴定出来过羽扇烷化合 I. INTRODUCTION r Lupine is a cycloalkane compound in which ring A, ring E are five-membered rings, rings B, C and D are six-membered rings, and ring A and ring E carry isopropenyl groups. It exists in some petroleum and source rocks. As early as the 1960s, many scholars studied the use of chromatograph and mass spectrometer lupine compounds, AIBurlingame, IRHil-1s and EVWhitehead (1966), respectively, in the Green River shale extract and Nigerian oil Identified in the lupine alkylate
