Efficacies of Novel Gemini Compounds Derived from Dibasic Acids as Multifunctional Additives for Tribological Applications

A series of new gemini compounds derived from the reaction of dibasic acids with N,N-diethyl-2-atninoethanol followed by reaction with p-toluene sulfonic acid were synthesized and characterized by means of Fourier transform infrared (FTIR) spectroscopy, nuclear magnetic resonance technique (H-1 NMR), and Mass spectral analyses. The synthesized compounds were used as multifunctional additives; particularly as antiwear agents, as friction reducing agents, and as corrosion inhibitors for tribological applications. To the best of our knowledge, this is the first :report describing the use of gemini compounds in tribological applications.
