Gas chromatographic study of methylstyrenes in the light-oil fraction of coal distillate using selective hydrogenation

Add time:08/24/2019    Source:sciencedirect.com

The catalytic hydrogenation of olefinic aromatic hydrocarbons, such as styrene, α- and β-methylstyrene, o-, m- and p-methylstyrenes and indene in the light-oil fraction was carried out by a selective method, the aromatic rings being kept intact. Gas chromatography was employed to identify the starting materials and the products.The chromatograms of the hydrogenated and non-hydrogenated samples which were obtained under identical conditions were compared. The qualitative and quantitative determination of these compounds was based on the shifts of the peaks after the hydrogenation process, and calculation of the new peak areas (e.g., the shift from α-methylstyrene to cumene), and it was therefore possible to identify methylstyrenes in the light-oil fraction from their well separated peaks in the chromatograms.
