Investigation of Surakhani light crude oil compounds as a case study using modern spectroscopic techniques

Abstract The complex application of modern analysis methods (FT-IR, NMR, GC–MS and UV/Vis) allowed us to study in detail the composition crude Surakhani light oil with a composition. An accurate comprehensive oils makes it easier find necessary field for them. For this purpose, studied was separated into two fractions, such as paraffinic–naphthenic aromatic (groups 1st, 2nd, 3rd tar), by absorption column chromatography. results show that is paraffin–naphthene-based contains 74% paraffin–naphthene, 11.15% hydrocarbons 14.8% gases. It has been shown group compounds mainly composed mono- bicyclic alkyl chains different lengths branches (with presence methylene methine groups). Based on parameters structural group, found portion H atoms nucleus chain 4.4–20.1% 79.9–95.6%, respectively. degree aromaticity approximately 50%, which proves these are alkylated. structure isolated paraffin–naphthene fraction also investigated spectroscopic techniques, determined iso- cycloalkanes lengths. As seen from obtained results, unlike other existing Absheron Peninsula, consists one- two-ring naphthene isostructured paraffinic hydrocarbons. petroleum isosubstituted relict, viz. biologically active sterane hopane used medicine. seems methodology developed industry can be fields Graphical abstract
