    Abstract: A composition including one or more monomethyl ester compounds represented by the formula: R1 is a monomethyl branched C15 to C19 alkyl group and R2 is an unsubstituted C2 to C30 linear alkyl group. The composition has a viscosity (Kv100) 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.

    Abstract: A composition that includes one or more compounds represented by the formula (R1)a(X)(R2)b wherein R1 and R2 are the same or different and are the residue of an alkyl group having from about 4 to about 40 carbon atoms, X is the residue of at least one polycyclic, heteroatom-containing, hydrocarbon compound, a is a value from 1 to about 8, and b is a value from 0 to about 8. The composition has a viscosity (Kv100) from about 2 to about 300 at 100° C. as determined by ASTM D-445, and a viscosity index (VI) from about −100 to about 300 as determined by ASTM D-2270. 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 for improving oxidative stability of a lubricating oil by using as the lubricating oil a formulated oil containing the composition.

    Abstract translation: 其中R1和R2相同或不同，是具有约4-约40个碳原子的烷基的残基，X是至少一个多环，含杂原子的烃化合物的残基，a是1 至约8，b为0至约8.该组合物在100℃下的粘度（Kv100）为约2至约300，根据ASTM D-445测定，粘度指数（VI）为 约为100至约300，如ASTM D-2270所测定。 本公开还涉及组合物的制备方法，润滑油基础油和含有该组合物的润滑油，以及通过使用含有该组合物的配制的油来提高润滑油的氧化稳定性的方法。
