Hexakis-addition [60] fullerene derivative and application thereof in lubrication field

Abstract

The invention discloses a hexakis-addition [60] fullerene derivative and an application thereof in the lubrication field; the hexakis-addition [60] fullerene derivative has the structural formula defined in the specification; addition positions of the hexakis-addition [60] fullerene derivative are all generated on [6,6] double bonds on an equator. Through introduction of 12 flexible ester chains onto hard C60, the solubleness is greatly increased, and the dispersion problem of [60] fullerene in lubricating oil is improved; through symmetric introduction of six long-chain ester groups to the periphery of a C60 sphere, the compound is endowed with viscoelasticity and toughness, and existence of the ester groups ensures the adsorbability of the compound on friction surfaces; with the introduction of long-chain alkyl, the oiliness of the compound can be increased, so as to better hinder direct contact between two friction pair surfaces and improve the lubricating performance of the lubricating oil. The hexakis-addition [60] fullerene derivative can be used as an anti-wear lubricating additive in the lubrication field.

Description

technical field [0001] The invention relates to a class of hexaaddition [60] fullerene derivatives and the application of the compound in the field of lubrication, which belongs to the field of organic synthesis and lubrication. Background technique [0002] About one-third of the metal materials in the world are consumed by oxidation corrosion and mechanical wear every year, and the loss in this area in my country is as high as hundreds of billions of yuan every year. Therefore, it is very important to prevent metal corrosion and improve lubrication and anti-wear properties. Antiwear additives commonly used in lubricating oils include sulfur antiwear agents, phosphorus antiwear agents, sulfur phosphorus antiwear agents, halogen antiwear agents, organometallic antiwear agents and boron antiwear agents. Because these additives are limited by environmental protection, energy saving, and existing processing technology conditions, it is urgent to research and develop new additi...

AI Technical Summary

Problems solved by technology

However, [60] fullerene is only soluble in a few non-polar solvents such as carbon disulfide, toluene, and benzene, so it is difficult to stably disperse in lubricating oil, and it is difficult to achieve the ideal effect of anti-wear and anti-friction

Guan Wenchao and others used free radical polymerization to prepare a series of water-soluble fullerene-organic molecular polymers, but the polymerization reaction system is complex, and the introduction of carboxyl groups will cause certain corrosion on the metal surface [Guan Wenchao, Shen Chunying, 2001,29,8; Lei Hong, Guan Wenchao, Luo Jianbin, Journal of Tsinghua University (Natural Science Edition), 2002,42, S1:S76-79]
