Abstract
A lubricant, which includes an ionic liquid including a conjugate base and a conjugate acid, wherein the conjugate acid has a group including a straight-chain hydrocarbon group having 6 or more carbon atoms, a pKa of an acid that is a source of the conjugate base in acetonitrile is 10 or less, and solubility of the ionic liquid to CF3(CHF)2CF2CF3 is 0.1 parts by mass relative to 100 parts by mass of CF3(CHF)2CF2CF3.
Claims7
A lubricant comprising:
- an ionic liquid including a conjugate base and a conjugate acid,
