LOW VISCOSITY LOW VOLATILITY LUBRICATING OIL BASE STOCKS AND PROCESSES FOR PREPARING SAME
20170137734 · 2017-05-18 ·

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


R.sub.1OR.sub.2

wherein R.sub.1 is a substituted or unsubstituted aryl or polyaryl group having from about 4 to about 40 carbon atoms, and R.sub.2 is a substituted or unsubstituted, linear or branched, alkyl group having from about 4 to about 40 carbon atoms. The composition has a viscosity (Kv.sub.100) 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.
