Abstract

In this work the de-acidification of dodecane was investigated using DBU based ionic liquid with thiocyanate SCN anion. The liquid-liquid equilibrium data for ternary mixture of {dodecane + naphthenic acid + DBU-HexSCN} were experimentally determined at a constant temperature and pressure. The ternary diagram shows that all the tie lines have a positive slope at all concentration of naphthenic acid, thus indicating that the ionic liquid is enough for the de-acidification of dodecane. The liquid-liquid equilibrium data was correlated using non-random two liquid (NRTL) model. An extremely good fit was obtained for all the tie lines using the NRTL model. © 2016 Published by Elsevier Ltd.
