Prathima, A.; Karthikeyan, S.; Radhi Devi, K.; Usha, K.; Shanthi, M. published the artcile< Environmental effect of lubricity additives through dielectric molecular parameters>, Synthetic Route of 104-76-7, the main research area is caprylic valeric acid additive lubricity.
Lubricant additives are chems., nearly always-organic or organometallic, that are added to oils in quantities of a few weight percent to improve the lubricating capacity and durability of the oil. Specific purposes of lubricant additives are improving the wear and friction characteristics by provision for adsorption and extreme pressure lubrication, improving the oxidation resistance, control of corrosion, control of contamination by reaction products, wear a and other debris, reducing excessive decrease of lubricant viscosity at high temperatures, enhancing lubricant characteristics by reducing the pour point and inhibiting the generation of foam. These properties depend upon the mol. interactions between the chem. additives. So that, this study target on investigating the mol. interactions through the dielec. parameters such as Kirkwood correlation factor, Excess permittivity, Bruggemann factor and Dipolar excess free energy in the lubricative binary mixtures,(1) caprylic acid + 2-ethyl-1-hexanol and (2) valeric acid + 2-ethyl-1-hexanol. The above dielec. parameters have been calculated from the exptl. measured values of capacitance and refractive index of mixtures, at temperatures 303 K, 313 K and 323 K. In the above studied systems, existence of short and long range, homo and hetero interactions are identified. The hetero interaction results in the formation linear as well as closed multimers in the mixture Due to the existing interactions, structural changes are found to take place.
