Abstract

In this study, the liquid-liquid equilibria for ternary systems of Normal alkanes (consisting of nonane, undecane and tridecane) + Methanol + Methyl ethyl ketone have been investigated experimentally at the temperatures of 278. 15, 288. 15 and 298. 15 K. The experiments of this study consist of the determination of the Two-phase region and the tie lines of each of these three systems. The two phase regions were found by the titration method, based on the cloud point determination. The tie lines were found by using gas chromatography on the samples of the phases in equilibrium. The effects of temperature and the hydrocarbon chain length of the n-alkanes were also studied. In addition, the tie lines of each system were modeled by the NRTL (Non Random Two Liquid) model. The calculated values of root mean squared deviations (1. 33, 1. 71, 0. 56 and 0. 87) show the acceptable results of the used model in this study.
