SOME METHODOLOGICAL APPROACHES TO STUDYING THE SOVIET EPOCH AT THE RUSSIAN HISTORY COURSES FOR HIGHER SCHOOL

The article considers the theoretical and methodological foundations for research practices applied while studying the Soviet period in the history ofRussia. The author reveals the methods of research of the Soviet reality and the channels of its influence on the modernity. He also defines the influence of the Soviet epoch symbols on the modern Russian daily occurrence. The author concludes that Russia will never go back to its Soviet past. But there has come into being a kind of stylistic model that presents such a return at the level of imitation

Anticorrosion Efficiency of Inhibitor Coatings Based on Ammonium Cation with Different Substituents: The Influence of Wettability and Molecular Structure

In this work, different cationic surfactants with various aliphatic and aromatic ammonium cations were used to prepare inhibitor coatings and were characterized by different techniques such as IR spectroscopy and NMR. The inhibitor coatings were prepared by electrografting on the steel surface and their anticorrosion properties were evaluated in different media (HCl, H2SO4 and NaCl solutions). The electrochemical potentiodynamic polarization technique was used to study the inhibition efficiency of the prepared coatings. The dependence of the wetting properties of the electrografted layer and its homogeneity on the molecular structure of the prepared surfactants was studied. Particular attention was paid to the relationship between the properties of these surfactants in terms of critical micellar concentration, packing and wetting, and the anti-corrosion efficiency of their coatings. In this paper, we discuss the synergistic inhibition effect and the anticorrosion efficiency

Synthesis and Anti-Knock Properties of Furfural Derivatives

Исследовательским методом оценены октановые числа растворов диэтилацеталя фурфурола и фурфуриламина в прямогонном бензине и установлены линейные зависимости октанового числа растворов изученных веществ от их концентрации. Рассчитаны октановые числа смешения диэтилацеталя фурфурола (106,0±3,8) и фурфуриламина (193,5±7,7). Предложен новый метод препаративного синтеза диэтилацеталя фурфурола прямым взаимодействием спирта и альдегида. Для смещения равновесия реакции пары воды из газовой фазы над раствором реагирующих веществ удаляются оксидом кальция. Оценена окислительная стабильность растворов фурфуриламина в прямогонном бензине: по показателю «индукционный период» (более 1000 мин) она соответствует требованиям ГОСТ 2084-77 при концентрации фурфуриламина менее 5 мас. %.Research octane numbers (RON) of the furfural diethyl acetal and furfurylamine solutions in straight-run gasoline were measured, and the liner dependences between the solution octane numbers and concentrations of furfural derivatives were found. Blending research octane numbers (BRON) for furfural diethyl acetal (106.0±3.8) and furfurylamine (193.5±7.7) are calculated. A novel method of syntheses of furfural diethylacetal by the direct interaction of the alcohol and the aldehyde is developed. To shift the reaction equilibrium a water vapour from gas phase over the reaction mass is removed by calcium oxide. Oxidative stability of the furfurylamine solutions in straight-run gasoline (test for induction period) was estimated. It corresponds to the GOST 2084-77 conditions at the furfurylamine concentrations less than 5 wt. % and exceeds value of 1000 mi

Tanachi-Moktakonsky oil and gas accumulation zone - potential object of combination of production and processing

Актуальность исследования обусловлена необходимостью воспроизводства и расширения ресурсной базы территории Красноярского края за счёт вовлечения в разработку нефтей и конденсатов сложного химического состава, содержащих меркаптаны, сероводород и серу. Цель: охарактеризовать состав и определить закономерности формирования нефтей и конденсатов ароматико-нафтено-метанового типа в Таначи-Моктаконской зоне нефтегазонакопления, расположенной на Бахтинском мегавыступе Сибирской платформы; разработать предложения по подготовке флюидов этой зоны до требований их транспортировки по трубопроводным системам на нефтеперерабатывающие заводы. Объекты: залежи нефти и конденсата ароматико-нафтеново-метанового состава в пределах территории Бахтинского мегавыступа западной части Сибирской платформы. Методы: геокартирование границ Таначи-Моктаконской зоны нефтегазонакопления в отложениях таначинской (горизонт А-I) нижнего-среднего кембрия (Є1-2), абакунской и моктаконской (A-V, A-VI) свит нижнего кембрия (Є1); изучение геологических условий и состава и свойств нефти и конденсата, полученных из этих горизонтов в скважинах Танчинской, Моктаконской площадей; анализ и обобщение материалов по очистке сероводород- и меркаптансодержащих нефти и газоконденсата на промыслах. Результаты. Бахтинский мегавыступ хоть и обладает широким развитием ароматико-нафтено-метановых нефтей и конденсатов, содержащих меркаптаны и серу, остаётся перспективной территорией, так как магматизм оказал негативное воздействие на первичные залежи нефти и конденсата главным образом в отложениях нижнего и нижнего-среднего кембрия. На основе анализа материалов бурения и состава пластовых флюидов оконтурена Таначи-Моктаконская зона нефтегазонакопления в отложениях таначинской, абакунской и моктаконской свит нижнего-среднего и нижнего кембрия. Концептуально решение проблемы использования нефти и конденсата сложного состава предлагается в рамках создания здесь пионерного территориального совмещения добычи и переработки углеводородов.The relevance of the research is determined by the necessity of reproduction and expansion of oilfields area resource base in the Krasnoyarsk region by involving in the development of oils and condensates of complex chemical composition containing mercaptans, hydrogen sulfide and sulfur. The main aim of the research is to characterize composition and to define the regularities of formation of oil and condensates aroma- tico-naphtene-methane type in Tanachi-Moktakonsky zone of oil and gas accumulation, located on Bakhtinsky megaledge of the Siberian platform; to develop proposals for preparation of fluids of this zone of oil and gas accumulation before requirements of their transportation through pipeline systems to refinery. Objectives of the research are the deposits of oil and condensate of aromatic-naphthenic-methane composition within the territory of the Bakhtinsky megaledge of the Western part of the Siberian platform. Methods: geomapping of borders of Tanachi-Moktakonsky zone of oil and gas accumulation in sediments tanachinsky (A-I horizon) lower-middle-Cambrian (Є1-2), abakunsky and moktakonsky (A-V, A-VI) of suites of the lower Cambrian (Є1 ); study of geological con- ditions and composition and properties of oil and condensate received from these horizons in wells of Tanachinsky, Moktakonsky areas; analysis and generalization of materials on cleaning a hydrogen sulfide- and mercaptans oil and gas condensate on crafts. Results. Although the Bakhtin megaledge has a wide development of aromatic-naphthene-methane oils and condensates containing mercaptans and sulfur, it remains a promising area, since magmatism has had a negative impact on primary deposits of oil and condensate mainly in the sediments of the lower and lower-middle Cambrian. Based on the analysis of drilling materials and composition of the reservoir fluids the Tanachi-Moktakonsky zone of oil and gas accumulation is contoured in sediments of tanachinsky, abakansky and moktakonsky suites of lower-middle and lower Cambrian. A conceptual solution to the problem of using oil and condensate of complex composition is proposed in the framework of the creation here of innovative territorial combination of production and processing of hydrocarbons

Novel Mesogenic Vinyl Ketone Monomers and Their Based Polymers

In the present research, we have synthesized new vinyl ketone monomers with mesogenic substituents, namely, 8-(3′-chloro-4′-pentyl-[1,1′-biphenyl-4-oxy)oct-1-en-3-one (BVK) and 8-[2′-chloro-4‴-octyl-[1,1′:4′,1″:4″,1‴-quaterphenyl-4-oxy]oct-1-en-3-one (QVK). The comparison of BVK, QVK, and previously synthesized 8-((4″-((1R,4S)-4-butylcyclohexyl)-2′-chloro-[1,1′,4′,1″-terphenyl]-4-yl)oxy)oct-1-en-3-one (TVK) has revealed that all of them are able to form crystals, while their ability to exhibit liquid crystalline behavior depends on the number of phenyl substituents attached to the para-position of the phenoxy group and is observed for TVK and QVK only. All of the monomers are able to achieve self-polymerization upon heating and free radical polymerization in bulk or in solution under the action of the common radical initiator AIBN. We have also succeeded in the RAFT polymerization of the synthesized vinyl ketones BVK and TVK using asymmetrical trithiocarbonates. The synthesized poly(vinyl ketones) exhibit LC behavior and are able to undergo photodegradation upon UV irradiation
