saturated isoprenoid hydrocarbon, 2,6,10-trimethyltetradecane, has been isolated from the Antrim Shale and has been characterized on the basis of capillary gas chromatography and mass spectrometry. This represents the first report of this isoprenoid alkane in crude oils and sediments. A standard C17 isoprenoid has been synthesized from farnesol. The possibility that a C30 isoprenoid, such as squalane, may be
从Antrim页岩中分离出AC 17饱和的类
异戊二烯烃
2,6,10-三甲基十四烷,并根据毛细管气相色谱法和质谱法对其进行了表征。这是原油和沉积物中这种类
异戊二烯烷烃的首次报道。由
法尼醇合成了标准的C 17类
异戊二烯。已经研究了C 30类
异戊二烯(例如
角鲨烷)可能是类
异戊二烯烷烃的前体的可能性。Antrim页岩中相对较小比例的C 17类
异戊二烯表明,
植醇是可能的前体。已经合成了两个C 19异构
烷烃,并将它们的质谱与另一个C 19进行比较异构烷,p烷。这些光谱的紧密相似性强调了必须对从原油和沉积物中分离出的有机化合物(尤其是碳氢化合物)分配结构,而无需其他物理测量结果的进一步确认。
