Abstract

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.

润滑油中多功能添加剂的作用效率

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。
