Study of structural parameters of petroleum acids and analysis of their possible negative impact on the environment by L. V. Ivanova, O. A. Stokolos, E. S. Demidenko, V. N. Koshelev

“…It is shown that the products isolated during leaching have a molecular weight of 294–574 amu and contain from 20 to 40 carbon atoms, most of which are part of the naphthenic structures. Along with petroleum acids, leaching products include hydrocarbons.Comparison of the structural parameters of the products isolated from the fractions of the studied oil with the data in the scientific literature allows us to qualify the acids contained in the oil of the Priozernoye field as being substances with high toxicity, which requires finding ways to solve the problem of ensuring the environmental safety of this region.…”
