Abstract
A procedure is developed for the determination of more than 60 individual sulfur-containing compounds (SCC) in liquid hydrocarbon raw materials and in liquid fuels using gas chromatography on a 25-m WCOT column, inner diameter 0.32 mm, with a nonpolar dimethylpolysiloxane stationary phase (layer thickness 5 μm) and chemiluminescence detection. SCC were identified by individual standard substances and published data. Quantitative determination was carried out by the internal standard method. The results of determination of individual SCC in petrol and stable gas condensate are presented. The most high-boiling SCC found in significant amounts (more than 0.005 wt % of sulfur) were C2-benzothiophenes (in petrol) and C4-dibenzothiophenes (in gas condensate).
