Densities, Viscosities and Excess Properties of Binary Liquid Mixtures of Methyl Tert-Butyl Ether (MTBE) with N-Methylaniline (NMA) from 308.15-318.15 K at 0.1 MPa

Abstract

Densities and viscosities of binary liquid mixtures of Methyl Tert-Butyl Ether (MTBE) with N-Methylaniline (NMA) at temperatures of 308.15, 313.15 and 318.15 K have been measured experimentally at atmospheric pressure over the entire range of composition. The densities and viscosities of MTBE and NMA binary mixture show a decreasing trend with the increase in MTBE composition at all temperatures. In addition, Jouyban-Acree equation has been used to predict the densities and viscosities where low standard deviations of 0.0025 and 0.0168 have been obtained. The excess molar volumes and viscosity deviation have been calculated and correlated with the Redlich-Kister equation where a good fit was obtained. Sigmoid shape of excess molar volumes has been obtained where negative excess molar volumes were obtained at high mole fraction of MTBE for all temperatures. Negative viscosity deviation has been obtained which showed the strength of chemical interaction in terms of hydrogen binding between unlike molecules.
