A composition including an ionic liquid alkyl ammonium salt (e.g., tetraalkylammonium cation and bis(trifluoromethanesulfonyl)imide anion) or an ionic liquid imidazolium salt (e.g., 1,3-dialkylimidazolium cation and bis(trifluoromethanesulfonyl)imide 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.
一种组合物包括离子液体烷基铵盐(例如,四烷基铵阳离子和双(三氟甲烷磺酰)亚胺阴离子)或离子液体咪唑盐(例如,1,3-双烷基咪唑阳离子和双(三氟甲烷磺酰)亚胺阴离子),具有足够的结构以在一种或多种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组分的配方油和离子液体烷基铵盐共油库存或离子液体咪唑盐共油库存作为次要组分来改善离子液体在润滑油中的溶解度的方法。
