Abstract

The present invention relates to the compound represented by formula (2), wherein, R3 is 1-methylundecyl, 1-ethyldecyl, 1-dodecyl, 1-methyltridecyl, 1- Any one of ethyl dodecyl and 1-tetradecyl is a hydrocarbon group with 12 or 14 carbons as the main component, and the ratio of the benzylic carbon of R3 to quaternary carbon is 30 to 40 mol%, and R4 is carbon In the branched hydrocarbon group having a number of 16-20, the total ratio of the benzylic carbon of R3 and R4 being a quaternary carbon is 42-100 mol%. m and n are real numbers satisfying 1.0≤m≤2.0 and 1.0≤n≤2.0 respectively, and 2.0≤m+n≤3.0.

Description

technical field [0001] The present invention relates to a hydrocarbon substitute of diphenyl ether and a lubricating oil for high temperature and a heat-resistant grease containing the compound. Background technique [0002] In recent years, with the miniaturization and weight reduction of various machinery and bearings, high-speed operation, and maintenance-free, in order to make lubricants such as lubricating oil and grease used under severe conditions such as high temperature, high speed, and high load, there are Lubricants with better heat resistance and oxidation resistance are essential. [0003] In bearing lubrication, when the service conditions are high temperature and high speed, the lubricating oil and grease used for lubricating undergo a temperature rise caused by a shortage of oil film, and / or thermal and oxidative deterioration, and as a result, promote the lubricating base oil Evaporation, which leads to the formation of sludge, which in turn leads to damage...
