摘要
本文介绍自原油分离含氧化合物,酯化混合酸和用毛细管气相色谱-质谱(GC-MS)鉴定其组分的方法。色谱-质谱分离并鉴定出C_8—C_(30)的脂肪酸、分子量为484和498的二对藿烷酸的立体异构体,烷基酚,邻苯二甲酸酯等,并首次发现石油中含有癸二酸二异辛酯类组分。
In crude oil from Henan province, five groups of oxygen-containing compound are identified
by capillary gas chromatography-mass spectrometer. They are fatty acids of 8-30 carbon atoms
having a molecular weight between 484 and 498; polycylic-acids of hopanoic series:phthalates;
alkylphenols; and diisooctyl esters of decanedioic acid. Their quantitative determination can also
be achieve by this method.
