Isothermal VLE and VE at 303.15 K for the Binary and Ternary Mixtures of Di-isopropyl Ether (DIPE) + 1-Propanol + 2,2,4-Trimethylpentane

Abstract

Isothermal vapor−liquid equilibrium (VLE) data at 303.15 K are reported for the binary systems of di-isopropyl ether (DIPE) + 1-propanol, DIPE + 2,2,4-trimethylpentane, and 1-propanol + 2,2,4-trimethylpentane and also for the ternary system of DIPE + 1-propanol + 2,2,4-trimethylpentane by using headspace gas chromatography. Additionally, the excess molar volumes (VE) at 303.15 K for the same systems were also determined by measured densities. The experimental binary and ternary VLE data were correlated with GE model equations and the VE were correlated with the Redlich−Kister equation for binary systems and the Cibulka equation for ternary system, respectively.
