本文介绍了石油馏分及芳烃浓缩物结构分析的一个新方法.利用烃分子折射率及分子等张比容的可加性原理,推导出的结构分析公式,可以计算油品的环数和分枝数.从本法计算所得结果与 Waterman 等的直接法结果比较,说明本法所得结果比一般常用的结构分析方法精确,应用范围亦广,所求得的分枝数目与同一个油经加氢后用 Boelhouwer等对饱和油的分枝数分析法所得者也相符合,但用本法可省去加氢的步骤.当不需要分析分枝度时,可以用简化的方法由比折射率,分子量,碳氢分析的数据计算总环数及芳烃环数.此外作者环探讨了用同样的步骤推导对含有烯烃的油品结构分析公式的可能性,得到了可以令人满意的结果.
In this paper, a new method for the structural analysis of petroleum fractions and aromatic condensates is introduced.Using the additive principle of hydrocarbon molecular refractive index and molecular isotope capacity, the structural analysis formula can be deduced to calculate the number of rings and branching. The results obtained by this method are compared with the results of the direct method by Waterman et al., Which shows that the results obtained by this method are more accurate and widely used than the commonly used methods for structural analysis. The number of branches obtained is the same as that of the same oil after hydrogenation Boelhouwer et al. Also agree with the data obtained from the branch number analysis of saturated oils, but the hydrogenation step can be omitted by this method.When the degree of branching is not to be analyzed, a simplified method can be used to calculate the ratio of refractive index, molecular weight, carbon Hydrogen analysis data were used to calculate the total number of rings and the number of aromatic rings. In addition, the authors discussed the possibility of derivatizing the analytical formulas of olefins containing olefins using the same procedure and obtained satisfactory results.
