Protic ammonium bio-based ionic liquid crystal lubricants

چکیده
Bis(2-hydroxyethyl) ammonium stearate (DES) protic ionic liquid crystal (PILC) has been added in 1 wt% and 2 proportion to di-bis(2-hydroxyethyl) succinate (DSU) (PIL) obtain (DSU+1%DES) (DSU+2%DES) lubricant blends. The new blends are non-Newtonian fluids with crystalline domains. Addition of PILC PIL reduces running-in friction coefficient more than 70% prevents surface damage, decreasing wear rate one order magnitude. Optical profilometry, optical scanning electron microscopy (SEM), energy dispersive (EDX) X-ray photoelectron spectroscopy (XPS) have used analyze surfaces after the tribological tests.

The phase behaviour of phytantriol in the protic ionic liquid (PIL) 1-methylimidazolium pentadecafluorooctanoate (MImOF) and four different MImOF-water compositions was investigated by small- and wide-angle X-ray scattering (SAXS/WAXS), cross polarised optical microscopy (CPOM) and infrared spectroscopy (IR). MImOF is a distinct protic ionic liquid in that it contains a fluorocarbon anion and a...
متن کاملA Review of Ionic Liquid Lubricants
Due to ever increasing demands on lubricants, such as increased service intervals, reduced volumes and reduced emissions, there is a need to develop new lubricants and improved wear additives. Ionic liquids (ILs) are room temperature molten salts that have recently been shown to offer many advantages in this area. The application of ILs as lubricants in a diverse range of systems has found that...
متن کاملProtic ionic liquids based on phosphonium cations: comparison with ammonium analogues.
Novel protic ionic liquids (PILs) based on a tributyl phosphonium cation have been synthesised and characterised, revealing that the phosphonium based ILs show high thermal stability, high ionic conductivity and facile proton reduction compared to the corresponding ammonium based ILs.
متن کاملCO2 absorption of polymers of ammonium-based ionic liquid monomers
The topic of global warming as a result of increased atomospheric CO2 concentration is becoming the most important environmental issue that the world faces today.[1] The capture and separation of CO2, especially CO2 from large point source, for example, fossil-fuel-fired electrical power–generation plants is critical to stabilize the atomospheric CO2 concentration.[2] The existing commercial CO...
