Effect of a Long Alkyl Chain in Protic Ionic Liquids Molecules on Tribological Properties at High Temperature
In this work, three protic ionic liquids (PILs) were newly synthesized to prepare thermally stable lubricants. The thermal stability of PILs increases with increasing ΔpKa, defined as the difference in the logarithm of the acid dissociation constant (pKa) between a Brønsted acid and a Brønsted base....
