WIPO Patent Application WO/2017/217297

Kind Code:

A1

Abstract:

[Problem] To provide a lubricant base oil which exhibits excellent biodegradability and lubricity (abrasion resistance) and also exhibits excellent rust-preventing properties against sea water. [Solution] In an ester that constitutes the lubricant base oil, the molar percentage Amol% of a constituent component (A) derived from pentaerythritol is 20-30 mol.%, the molar percentage Bmol% of a constituent component (B) derived from a straight chain fatty acid having 14-22 carbon atoms is 55-79 mol.%, the molar percentage Cmol% of a constituent component (C) derived from adipic acid is 1-15 mol.%. The molar ratio (Cmol/Bmol) of the constituent component (B) derived from a straight chain fatty acid having 14-22 carbon atoms and the constituent component (C) derived from adipic acid is 0.02-0.25, and the hydroxyl value of the ester is 10-100 mg KOH/g.
