The paper presents a technology for producing base oil by oxidizing organosulfur compounds, contained in petroleum distillates and deasphaltisates, with hydrogen peroxide in the presence of vegetable (rapeseed and castor) oils, followed by extraction of oxidates and dewaxing of raffinates. Extraction of the resulting oxidized mixture (oxidate) was carried out with N-methylpyrrolidone. The content of rapeseed oil contained in the raffinate and extract was determined. The extract solution from a medium-viscosity oil distillate was cooled to obtain a secondary raffinate represented by a sulfoxide concentrate. The secondary raffinate was used as a base oil for producing a lubricant with high tribological properties for use in heavily loaded friction units. The rapeseed oil remained in the raffinate improves its viscosity index and lubricating properties. The raw materials and obtained raffinates were analyzed to assess their physicochemical and tribological properties.

本文介绍了一种生产基础油的技术,即在植物油(菜籽油和蓖麻油)存在的情况下,用过氧化氢氧化石油馏分油和脱盐油中所含的有机硫化合物,然后萃取氧化物并对脱蜡物脱蜡。所得氧化混合物(氧化物)用 N-甲基吡咯烷酮萃取。测定了浸出物和萃取物中菜籽油的含量。将中等粘度油蒸馏物的萃取液冷却,得到以亚砜浓缩物为代表的二次馏分。二次馏出物被用作基础油,用于生产具有高摩擦学特性的润滑油,供重载摩擦装置使用。残留在糠酸盐中的菜籽油提高了其粘度指数和润滑性能。对原材料和所得糠油进行了分析,以评估它们的物理化学和摩擦学特性。

A corrosion inhibitor composite was developed for carbon dioxide corrosion and it was adapted to the requirements of dosage, protective capacity, temperature characteristics, and compatibility with other reagents. The development process and the main requirements, observance of which was monitored, are described stage-by-stage. The outcome of the conducted research was two grades of a carbon dioxide corrosion inhibitor based on an imidazoline derivative. The difference between the developed composites lies in the solvent type and, correspondingly, in the temperature characteristics (flash and dew points). The influence of the amount of the active base on the effectiveness of the composite was evaluated and the optimum content of the components in the corrosion inhibitor was found. The importance of flash and dew points for corrosion inhibitors is underscored and a way of controlling these composite indicators is proposed.

A study was carried out on benzyl alkoxycarbonyl methyl disulfides as multifunctional additives to lubricating oils. Results are given for testing the anticorrosion, anti-wear, anti-microbial action of previously synthesized benzyl alkoxycarbonyl methyl disulfides containing several functional groups. Efficiency was demonstrated for a series of benzyl alkoxycarbonyl methyl disulfides. Depending on their composition and structure, these disulfides improve the anticorrosion, anti-wear, and antimicrobial properties of oils. The antimicrobial properties of these compounds were studied as components of M-11 oil. The synthesized compounds in concentration 0.5-1.5 mass % enhance the resistance of mineral oil to biological damage and also display antimicrobial and antifungal activity. These compounds are more efficient than sodium pentachlorophenolate, which is a commonly used biocide. Testing in a four-ball friction machine indicates that these compounds possess anti-wear properties. Our derivatograph data on the thermal stability of these additives are in accord with the results of thermoanalytical testing of commercial additives.

对作为润滑油多功能添加剂的苄基烷氧基羰基甲基二硫化物进行了研究。研究结果表明,以前合成的含有多个官能团的苄基烷氧基羰基甲基二硫化物具有防腐蚀、抗磨损和抗微生物作用。一系列苄基烷氧基羰基甲基二硫化物的功效得到了证实。根据其组成和结构的不同,这些二硫化物可以改善油类的防腐、抗磨和抗菌性能。我们研究了这些化合物作为 M-11 油成分的抗菌特性。浓度为 0.5-1.5 质量%的合成化合物增强了矿物油对生物破坏的抵抗力,并显示出抗菌和抗真菌活性。这些化合物比常用的杀菌剂五氯酚钠更有效。在四球摩擦机中进行的测试表明,这些化合物具有抗磨损特性。我们关于这些添加剂热稳定性的衍生图数据与商用添加剂的热分析测试结果一致。
