Abstract
This research focuses on the three organic solvents (Benzene C6H6, Toluene C6H5âCH3 and n-Hexane C6H14) different in the polarity and dielectric constant, which were subsequently evaluated as the solvents to reduce the aromatic content (XA) in the products of petroleum fraction like lubricants oils. The additives were blending with three samples of lubricants oils at mixing ratio ranging (13%, 23 and 37.5%), and the samples were characterizing by viscometer according to the ASTM D-445 and refractive index (RI) by Abbi refractometric with assist of n-d-m method. The reduction in the (XA) is starting with benzene then various at n-hexane and increasing with toluene were obtained for the samples of lubricants oils treated. Good result obtained with benzene solvent were 0.2966 (XA) at mixing ratio 37.5% in sample 2, also for reflectivity (RI) same case, but was various for other solvents. One of the important studies, n-d-m method with refractive index (RI) and viscosity showed good information to classify the aromatic content in case of the additions with suitable solvents. © 2020 Zibeline International Publishing Sdn.
