Abstract

Using a reaction between secondary amines, sodium hydroxide, and carbon disulfide followed by introducing methyl iodide into the reaction mixture, we synthesized and characterized a number of dialkyldithiocarbamic acid methyl esters that contained n-alkyl and iso-alkyl groups (C₂–C₅). Tribological performance data were obtained for the compounds synthesized as they were added to synthetic lubricants. The additives were demonstrated to markedly improve the antiwear, antiseizure, and antifriction properties of the resultant lubricating compositions. The effects of the concentration and structure of the esters on the friction and wear parameters of the lubricants were investigated.

二烷基二硫代氨基甲酸甲酯在润滑组合物中的摩擦学性能

摘要

通过仲胺、氢氧化钠和二硫化碳之间的反应，然后将甲基碘引入反应混合物，我们合成并表征了许多含有正烷基和异烷基（C ₂ -C ₅ ）的二烷基二硫代氨基甲酸甲酯。 ）。当合成的化合物添加到合成润滑剂中时，获得了摩擦学性能数据。添加剂被证明显着改善了所得润滑组合物的抗磨损、抗咬合和抗摩擦性能。研究了酯的浓度和结构对润滑剂摩擦磨损参数的影响。
