Improving the efficiency of oil refineries by developing the production of high-quality oils

Subject. This article discusses the efficiency of Russian oil refining complexes at the present stage of the oil industry's development. Objectives. The article aims to consider reserves to improve the efficiency of petroleum oil production in Russia and describe some aspects of the domestic oil refining complexes' efficiency improvement. Methods. For the study, I used the systems analysis, observation, comparison, generalization, and the method of hypothetico-deductive reasoning. Results. Based on an analysis of the main advantages and disadvantages of alternative ways of producing high-quality petroleum oils, the article describes the possibilities and ways of modernizing the petroleum oil production. Conclusions. The considered ways of modernizing the production of petroleum oils will help improve the economic efficiency of Russian oil refineries through reducing the technological equipment operating costs and adding to the oil refining depth.

Study of phosphorus-containing compounds as anti-seize and anti-wear additives for transmission and engine oils

Dithiophosphoric acid esters containing various functional groups have been synthesized. On the basis of allyloxybenzyl- and allyloxymethylbenzylchlorides, as well as sodium diisopropyldithiophosphate, allyloxybenzyl- and allyloxymethylbenzyldialkyldithiophosphates were obtained, respectively. 5-methyl-2-hydroxyphenylcarbonylmethyldiisopropyldithiophosphate was synthesized by the interaction of 5-methyl-2-hydroxy-chloroacetophenone and sodium diisopropyldithiophosphate. The synthesized compounds were studied as anti-wear and anti-seize additives for lubricating oils. Were also investigated their thermo-oxidative and anticorrosive properties. It was found that all synthesized compounds provide an improvement in the anti-wear and anti-seize properties of petroleum oils, and the efficiency depends on the presence of certain functional groups in the molecules of additives.
