Abstract

A compound that can be represented by formula (2). In said formula, R3 represents a C12 or C14 hydrocarbon group consisting primarily of a 1-methylundecyl group, a 1-ethyldecyl group, a 1-dodecyl group, a 1-methyltridecyl group, a 1-ethyldodecyl group, or a 1-tetradecyl group, and the molar percentage of said hydrocarbon groups in which the benzylic carbon is quaternary is between 30 mol% and 40 mol%, inclusive; R4 represents a C16-20 branched hydrocarbon group; the sum of the molar percentage of the hydrocarbon groups represented by R3 in which the benzylic carbon is quaternary and the molar percentage of the hydrocarbon groups represented by R4 in which the benzylic carbon is quaternary is between 42 mol% and 100 mol%, inclusive; and m and n represent real numbers that satisfy the relations 1.0 ≤ m ≤ 2.0, 1.0 ≤ n ≤ 2.0, 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...
