A composition including one or more diester compounds represented by the formula as defined herein. The 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. 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 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.
一种组合物,包括一种或多种由本文定义的式所代表的二酯化合物。根据 ASTM D445 测定,该组合物在 100°C 时的粘度 (Kv100) 约为 1 cSt 至约 10 cSt;根据 ASTM D2270 测定,该组合物的粘度指数 (VI) 约为 -100 至约 300;根据 ASTM D5800 测定,该组合物的 Noack 挥发性不大于 50%。一种用于生产该组合物、润滑油基础油和含有该组合物的润滑油的工艺,以及一种通过使用含有该组合物的配制油作为润滑油来改善润滑油的热稳定性和氧化稳定性、极性添加剂的溶解性和分散性、沉积物控制和牵引力控制中的一项或多项性能的方法。
