The paper presents the results of fraction and structural-group composition of acids and phenols of Garbi Absheron field oil. Studied oil is heavy, tarry, low paraffinic. The acids and phenols have been purified from the oil with their differentiation on the free and associated (in the form of compound esters) forms.

Free acids and phenols were purified from the oil via alkali extraction. Their associated forms were purified after saponification of the oil released from the samples.

To study the structure-group content of acids and phenols, proton-magnetic resonance spectroscopy method was used. Obtained results showed that acidic oxygen-containing compounds in Garbi Absheron field oil predominantly consist of associated acids and phenols in the form of compound esters. Middle molecules of these phenols contain condensed naphtenic-aromatic cycles, the acids by their structure belong to the derivatives of hydrocarbons of paraffin series of CH3 residual-substitutes.
