  • Patent number: 4668839
    Abstract: A process is described for separating and identifying organic sulphur compounds in petroleum distillates which comprises subjecting an aromatic-containing fraction to chromatography in a dual packed silica gel-alumina column employing pentane-ethyl acetate as a solvent to obtain a sulphur-containing eluate and analyzing the sulphur-containing eluate by gas chromatography and mass spectrometry. The aromatic-containing fraction is usually a naphtha fraction or a light gas oil fraction, with the gas oil fraction being subjected to chromatography on a silica gel column to obtain an aromatic fraction which is then subjected to the chromatography in the above silica gel-alumina column.
