English Title : Triarylimidazoles as potent antiwear agents: Eco-friendly synthesis and materialistic approach
English Abstract : The load-carrying capacity and wear properties of selected triaryl substituted imidazoles were evaluated using a four-ball test machine. These derivatives show better antiwear performance in comparison to paran oil alone, which is con rmed by an Atomic Force Microscope. Thus, these substituted imidazole derivatives can be used asan antiwear agent for steel balls. Triarylimidazoles were synthesized by a one pot three component reaction assisted by recyclable and novel 1-ethyl-3-methylbenzimidazolium iodide [Embim]+I􀀀 in ecofriendly aqueous condition. This inexpensive, easily synthesized catalyst eciently catalyzes the condensation of 1,2-diketones, aromatic aldehyde and ammonium acetate. Besides the recycling of the catalyst, the short reaction time, excellent product yield and use of water display both economic and environmental advantages.
English Keywords : Eco friendly; Benzimidazolium ion, 2,4,5- triarylsubstituted imidazole; Water.
