Low viscosity low volatility lubricating oil base stocks and methods of use thereof

A composition comprising one or more compounds selected from the group consisting of dihexyl 2-octyladipate, diheptyl 2-octyladipate, and dipentyl 2-dodecyladipate;

• wherein said composition has a viscosity (Kv100) from about 1 cSt to about 10 cSt at 100° C. as determined by ASTM D445, a viscosity index (VI) from about −100 to about 300 as determined by ASTM D2270, and a Noack volatility of no greater than 50 percent as determined by ASTM D5800;
• wherein said one or more compounds are produced by a process comprising reacting a substituted or unsubstituted alcohol having a hydrogen attached to a beta carbon thereof with a substituted or unsubstituted carboxylic diacid or anhydride, optionally in the presence of a catalyst and a solvent, under reaction conditions sufficient to produce said one or more compounds.

A lubricating oil base stock comprising one or more compounds selected from the group consisting of dihexyl 2-octyladipate, diheptyl 2-octyladipate, and dipentyl 2-dodecyladipate;
