Abstract
Ionic liquids possess different properties which make them a high potential as lubricants. In our work series of five ammonium salts ionic liquids were synthesized by using different C-chain carboxylic acids with ethanol amines and evaluated. The physicochemical properties and rheological behavior investigated for their potential use as synthetic lubricants. The prepared Ils show high thermal stability, good fluidity characters and the viscosity increases with increasing C-number (become thicker) which converted from liquid phase to semisolid phase (grease). Ia-Ic show Newtonian behavior behavior for and pseudoplastic behavior for Id and Ie.
