Abstract
The initial information for calculating the physical, chemical, and operational properties of gasoline is data on its group composition. The complex composition of gasoline fractions (according to capillary gas chromatography (CGC), comprising about 150–250 components) greatly complicates the rapid determination and identification of unsaturated hydrocarbons, which are the most important part of gasoline. As a rule, it is not possible to achieve complete separation of chromatographic peaks even on highly efficient 100-meter capillary columns. Poor reproducibility of the properties of capillary columns requires a large number of comparison samples, which complicates the identification of the separated components. A combination of high-performance liquid chromatography (HPLC) and CGC methods allows simplifying the methodology and increasing the accuracy and rapidity of the analysis.
期刊介绍：
Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas.
Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
