Abstract: 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.

Abstract: Methods are provided for producing Group II base stocks having high viscosity and also having one or more properties indicative of a high quality base stock. The resulting Group II base stocks can have a viscosity at 100° C. and/or a viscosity at 40° C. that is greater than the corresponding viscosity for a conventional Group II base stock. Additionally, the resulting Group II base stocks can have one or more properties that are indicative of a high quality base stock.

Abstract: Methods are provided for producing lubricant base oils from petrolatum. After solvent dewaxing of a brightstock raffinate to form a brightstock base oil, petrolatum is generated as a side product. The petrolatum can be hydroprocessed to form base oils in high yield. The base oils formed from hydroprocessing of petrolatum have an unexpected pour point relationship. For a typical lubricant oil feedstock, the pour point of the base oils generated from the feedstock increases with the viscosity of the base oil. By contrast, lubricant base oils formed from hydroprocessing of petrolatum have a relatively flat pour point relationship, and some of the higher viscosity base oils unexpectedly have lower pour points than lower viscosity base oils generated from the same petrolatum feed. The base oils from petrolatum are also unusual in yielding both high viscosity and high viscosity index and can be generated while maintaining a high yield.

Abstract translation: 提供从凡士林生产润滑油基础油的方法。 在明亮的原料萃余液的溶剂脱蜡后，形成光油基础油，产生凡士林作为副产物。 可以加氢处理矿脂以高产率形成基础油。 由凡士林加氢处理形成的基础油具有意想不到的倾点关系。 对于典型的润滑油原料，由原料产生的基础油的倾点随着基础油的粘度而增加。 相比之下，通过加氢处理矿脂形成的润滑剂基础油具有相对平坦的倾点关系，并且一些较高粘度的基础油意外地具有比由相同凡士林饲料产生的低粘度基础油更低的倾点。 来自凡士林的基础油在产生高粘度和高粘度指数方面也是不寻常的，并且可以在保持高产率的同时产生。
