Document Type and Number:
WIPO Patent Application WO/2017/217295
Kind Code:
A1
Abstract:
[Problem] To provide a lubricant base oil having excellent biodegradability and excellent low-temperature fluidity and capable of providing excellent extreme pressure performance when an extreme pressure additive is blended therein. [Solution] An ester constituting a lubricant base oil and having a molar percentage Amol% for a trimethylolpropane-derived constituent component (A) of 25-42 mol%, a molar percentage Bmol% for a C8-12 monovalent linear saturated fatty acid-derived constituent component (B) of 33-55 mol%, a molar percentage Cmol% for an adipic acid-derived constituent component (C) of 12-34 mol%, and a molar percentage for a lauric acid-derived constituent component in the C8-12 monovalent linear saturated fatty acid-derived constituent component (B) of 5-50 mol%. (BCOOH + CCOOH)/AOH = 0.90 to 1.02 (AOH indicates the hydroxyl group equivalent for the trimethylolpropane-derived constituent component (A); BCOOH indicates the carboxyl group equivalent for the C8-12 monovalent linear saturated fatty acid-derived constituent component (B); and CCOOH indicates the carboxyl group equivalent for the adipic acid-derived constituent component (C)).
