A composition including an ionic liquid alkylammonium salt (e.g., tetraalkylammonium cation and bis(2-ethylhexyl)phosphate anion), or an ionic liquid imidazolium salt (e.g., 1,3-dialkylimidazolium cation and bis(2-ethylhexyl)phosphate anion), that have a structure sufficient to exhibit at least partial solubility in one or more Group I-V base stocks. The disclosure also relates to a lubricating oil base stock and lubricating oil containing the composition, a multifunctional functional fluid containing the composition, and a method for improving solubility of an ionic liquid in a lubricating oil by using as the lubricating oil a formulated oil including a lubricating oil base stock as a major component, and an ionic liquid alkylammonium salt cobase stock, or an ionic liquid imidazolium salt cobase stock, as a minor component.
该组合物包括离子液体烷基铵盐(例如,四烷基铵阳离子和双(2-乙基己基)磷酸根离子)或离子液体咪唑盐(例如,1,3-二烷基咪唑阳离子和双(2-乙基己基)磷酸根离子),其结构足以在一种或多种I-V族基础油中至少部分溶解。本公开还涉及包含该组合物的润滑油基础油和润滑油,包含该组合物的多功能功能液体以及通过使用包括润滑油基础油作为主要成分的配方油和离子液体烷基铵盐共基础油或离子液体咪唑盐共基础油作为次要成分,以提高离子液体在润滑油中的溶解度的方法。
