Excess Enthalpy and Vapor-Liquid Equilibrium at Atmospheric Pressure for the Binary Systems 2-Methyl-2-propanol+2,4,4-Trimethyl-1-pentene and 2-Butanol+2,4,4-Trimethyl-1-pentene

摘要

Excess molar enthalpies were measured for the binary systems 2-methyl-2-propanol+2,4,4-trimethyl-1-pentene at 300 K and for 2-butanol+2,4,4-trimethyl-1-pentene at 298 K.Vapor-liquid equilibria were also measured for the same systems at atmospheric pressure with a circulation still,and the liquid and condensed vapor phase samples were analyzed with a gas chromatograph.The experimental data were correlated with a Wilson activity coefficient model.Experimental results and the fitted model were also compared with the predictive activity coefficient model UNIFAC (Dortmund).
