“…This principle was examined, as illustrated in Figure 2, using a sample of straight-run gas oil (Table I) with methylcyclohexane (MCH) as the weak developer and ethyl alcohol as the strong developer. The results show that this procedure eliminates mixing between saturates and aromatics, as reported in the literature (5,10). However, the aromatic fraction remains a complex mixture which cannot be readily characterized in terms of mono-, di-, and tricyclic aromatic content.…”

In analyzing mineral oils, gas oils, etc., in terms of groups of molecules of the same hydrocarbon type, it is desirable to separate the sample into fractions, each of which contains a single hydrocarbon type. Of the separation processes useful for this purpose, chromatography is outstanding. Three chromatographic methods of analysis were examined in a study of the hydrocarbon type composition of a IN THE study of petroleum refining processes it is frequently necessary to determine compositions of liquid hydrocarbons boiling in the gas oil and higher ranges. The approach to the analysis of these petroleum fractions has resolved itself into three lines of attack during recent years-i.e., analysis in terms of individual hydrocarbons, number of carbon atoms in rings and in alkyl chains, and molecular types.

“…The principal requirements were that a small quantity of stock be used, and that the analysis be completed within a relatively short time Allibone [1] showed that fractionation by adsorption could be used to obtain separation of petroleum fractions of high molecular weight. Hibbard (£) and Lipkin (6) used adsorption methods for separation of oils in the lubricating oil range. It was necessary for the present purpose to include deasphalting and dewaxing steps and to devise a means of obtaining a continuous relationship between properties (particularly viscosity index) and yield over the entire range of molecular types of the lubricating oil fraction.…”

The possibility of paper‐chromatographic identification of mixtures of polycyclic aromatic hydrocarbons has been studied. In order to decrease the hydrophilic character of filter paper, it was either acetylated or impregnated with alumina, propylene glycol, Vaseline or silicone. The systems studied were: anthracene and methylated anthracenes; fluorene and methylated fluorenes; phenanthrene, fluorene and anthracene; mixtures of tricyclic and of polycyclic hydrocarbons (found in the ‘chrysene fraction’). Some success was achieved with separations in these systems.
