SYNTHETIC TRACTION FLUID.

摘要

This new synthetic traction fluid is prepd. by compounding as a base oil a monoester, diester or triester represented by general formula (I), derivatives or mixtures of these, where Y is gp. (i) or -OH (in which A' is an ester bond of type -COO- or -OOC-, R1 is a hydrogen atom or one to three groups chosen from 1-8C alkyl groups (preferred 1-4C)) R2 represents one to three members, the same or different, selected from among a hydrogen atom and 1-8C alkyl groups, and (I) does not represent glycerol. Typically R2 is H- or CH3-. This synthetic traction fluid can also be prepared by adding to the aforementioned ester a second component (1-70 wt.%) consisting of a branched poly-alpha-olefin or a mono- or di-ester having two cyclohexyl rings.
