A composition that includes one or more compounds represented by the formula
R
1
—O—R
2
wherein R
1
is a substituted or unsubstituted aryl or polyaryl group having from about 4 to about 40 carbon atoms, and R
2
is the residue of a substituted or unsubstituted glycol ether having from about 4 to about 40 carbon atoms. The composition has a viscosity (Kv
100
) 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 for improving one or more of oxidative stability, solubility and dispersancy of polar additives of a lubricating oil by using as the lubricating oil a formulated oil containing the composition.
一种包括一个或多个化合物的组合物,其表示为R1—O—R2,其中R1是具有大约4到大约40个碳原子的取代或未取代芳基或多芳基基团,而R2是具有大约4到大约40个碳原子的取代或未取代乙二醇醚的残基。该组合物在100°C下通过ASTM D-445确定的粘度(Kv100)约为1到约10厘斯特,通过ASTM D-2270确定的粘度指数(VI)约为-100到约300,通过ASTM D-5800确定的Noack挥发性不大于50%。该公开还涉及生产该组合物的方法,含有该组合物的润滑油基础油和润滑油,以及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氧化稳定性、溶解性和极性添加剂的分散性的方法。
