This petroleum belongs to the petroleum of heavy type (ρ4 20-0.9505g/cm3), is characterized by the small exit of petrol and light hydrocarbon fractions, by the low content of general sulfur and low freezing point.Hydrocarbon composition of petroleum fractions was studied by gas-chromatography and mass spectrometry methods. It was established that in isomeric alkanes the content of the mono substituted isomers predominates over the disubstituted isomers. The amount of saturated hydrocarbons - paraffins and cycloalkanes in the total composition was 93 %, and the ratio of isoparaffins and n-paraffins was about 1:3.enmtsarekhevi petroleum, light hydrocarbon fractions, hydrocarbonic group composition of the oil fractions, method of aniline, GS-MS methodArticle
