A novel approach to improve the oil miscibility and incorporate multifunctionality in ionic liquids as lubricant additives

Publisher: Royal Society of Chemistry (RSC)

Date: 2021

DOI: 10.1039/D0CP05295G

Abstract: Recently ionic liquids (ILs) have shown promising tribological properties as additives in base oils however their lack of miscibility is a problem, with very few ILs being compatible with lubricant oil formulation (non-polar base oils).

Abstract: The present study investigated the synthesis of novel, oil miscible, multifunctional, silane functionalized imidazoline-based ionic liquids (ILs) with an emphasis towards halogen, sulfur and phosphorous free lubricant additives to replace the conventional additives (ZDDP, MoDTC, etc.), for which there are environmental concerns. These ILs were prepared in different concentrations and proved to be oil miscible for a short time. This stability was improved to over a year using sorbitan trioleate as an emulsifier additive. These additives performed well in reducing friction and wear when investigated on steel-steel contacts at a 5 wt% concentration, with improvements for the TPEIPS BEHP containing blend of up to 39% and 53%, respectively, as compared to the base oil. SEM and EDS analysis shows a phosphorous and oxygen rich tribo-film formation for this combinations. These ILs were further tested to determine their effect on properties such as viscosity, thermal stability, elastomeric and antifoaming compatibility. These new ILs work towards the discovery of environmentally friendly additives for tribological processes.
