| 摘 要： | 采用毛细管气相色谱将汽油试样做单体烃组成分析。按碳数归纳出PIONA族组成分布,用各单体烃的辛烷值、密度、蒸汽压、沸点、热值等物性数据和各单体烃的体积百分含量计算出汽油的物性指标,其中辛烷值以数十个试样的分析结果与CFR机测定值进行关联和线性回归分析,获得准确的计算汽油辛烷值的方程并以广石化各种汽油为例做了考察。

| Abstract: | The hydrocarbon composition of gasoline has been analyzed by automatic capillary chromatography. The distribution of components of the PIONA group is found according to the number of carbon atom. The eight quality indexes of gasoline are calculated from the physical properties such as octane number, density, vapor pressure and the volume percentage contents of the components. As to the octane number, the analytical results of dozens of samples are correlated with the values determined by CFR method, and linear regression analysis is done to obtain the correct equation for calculating the octane number. |
