Abstract
A composition including one or more monomethyl ester compounds represented by the formula: Ris a monomethyl branched Cto Calkyl group and Ris an unsubstituted Cto Clinear alkyl group. The composition has a viscosity (Kv) from 1 cSt to 10 cSt at 100° C. as determined by ASTM D445, a viscosity index (VI) from −100 to 300 as determined by ASTM D2270, a pour point from 0° C. to −50° C. as determined by ASTM D97, and a Noack volatility of no greater than 50 percent as determined by ASTM D5800. A process for producing the composition, a lubricating oil base stock and lubricating oil containing the composition, and a method for improving one or more of cold flow properties, thermal and oxidative stability, solubility and dispersancy of polar additives, deposit control and traction control in a lubricating oil by using as the lubricating oil a formulated oil containing the composition.
