Abstract

See full text

A composition that includes one or more compounds represented by the formula

description='In-line Formulae' end='lead'R1—O—R2 description='In-line Formulae' end='tail'

wherein R1 is a substituted or unsubstituted aryl or polyaryl group having from about 4 to about 40 carbon atoms, and R2 is a substituted or unsubstituted, linear or branched, alkyl group having from about 4 to about 40 carbon atoms. The composition has a viscosity (Kv100) from about 1 to about 10 cSt at 100° C. as determined by ASTM D-445, a viscosity index (VI) from about −100 to about 300 as determined by ASTM D-2270, and a Noack volatility of no greater than 50 percent as determined by ASTM D-5800. The disclosure also relates to a process for producing the composition, a lubricating oil base stock and lubricating oil containing the composition, and a method of reducing boundary friction and improving dispersancy of polar additives of a lubricating oil by using as the lubricating oil a formulated oil containing the composition.
