Abstract: Methods are provided for producing Group III base stocks having high viscosity and also having one or more properties indicative of a high quality base stock. The resulting Group III base stocks can have a viscosity at 100° C. and/or a viscosity at 40° C. that is greater than the corresponding viscosity for a conventional Group III base stock. Additionally, the resulting Group III base stocks can have one or more properties that are indicative of a high quality base stock.

Abstract: A composition that includes one or more compounds represented by the formula R1—O—R2 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.
