Document Type and Number:
WIPO Patent Application WO/2020/080269
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a power transmission lubricant oil base oil that has a high coefficient of traction and flash point and has excellent low temperature fluidity. The present invention relates to the power transmission lubricant oil base oil that comprises a compound represented by general formula (1) (In the formula, R1 to R5 are the same or different, each indicating a hydrogen atom or a linear or branched alkyl group having 1 to 4 carbon atoms, any two of R1 to R5 may be bonded to each other to form an alkylene group having 1 to 4 carbon atoms, and the two R1s, the two R2s, the two R3s, the two R4s, and the two R5s may be the same or different. X indicates a divalent group which is obtained by removing two hydroxyl groups from a branched aliphatic diol having 4 to 12 carbon atoms and which does not contain quaternary carbon, the two hydroxyl groups being primary alcohol).
