The group hydrocarbon composition of base summer diesel fuels of various Russian refineries was investigated using methods of gas and high performance liquid chromatography. It is shown that the experimental data obtained by these methods, precisely pertaining to the content of normal paraffins and the total content of paraffinic-naphthenic and aromatic hydrocarbons, do not provide sufficient information for predicting physicochemical and performance properties of diesel fuels. For a more detailed study of the hydrocarbon composition of diesel fuels, use was made of the method of two-dimensional gas chromato-mass spectrometry, which made it possible to determine the ratio of normal and isoalkanes and the content of mono-, bi- and polycyclic naphthenic and aromatic hydrocarbons and to explain the differences between hydrocarbon compositions of fuels with similar performance characteristics.

使用气相色谱法和高效液相色谱法研究了俄罗斯各炼油厂夏季基础柴油的组烃组成。结果表明，通过这些方法获得的实验数据，精确地与正链烷烃的含量和链烷烃-环烷烃和芳烃的总含量有关，不能为预测柴油燃料的物理化学和性能特性提供足够的信息。为了更详细地研究柴油的碳氢化合物组成，使用二维气相色谱-质谱法，可以确定正烷烃和异烷烃的比例以及单、
