ALKANOLAMINE, FRICTION-REDUCING AGENT, AND LUBRICATING OIL COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2018/139326
Kind Code:
A1
Abstract:
Provided are: a friction-reducing agent containing neither sulfur nor phosphorus and having excellent friction-reducing properties; and a lubricating oil composition containing the friction-reducing agent. The friction-reducing agent comprises an alkanolamine represented by formula (1). [In formula (1), A1 and A2 each independently represent a hydroxy group or a hydrogen atom, both A1 and A2 being not hydrogen atoms; R1 represents a C30 or lower hydrocarbon group; R2 to R6 each independently represent a hydrogen atom or a C30 or lower hydrocarbon group; and m and n are each independently an integer of 0-10.]
