Isothermal Vapor-Liquid Equilibria for Methyl-2,2-dimethylethyl Ether + 2-Methylpropan-2-ol, Diethyl Ether + Ethyl-2,2-dimethyletyle Ether, 2-Methyl-2-butene + (2-Methylbutan-2-ol), and Diisopropyl Ether + Octane

摘要

Isothermal vapor-liquid equilibrium data for four binary systems methyl-2,2-dimethylethyl ether + 2-methylpropan-2-ol, diethyl ether + ethyl-2,2-dimethylethyl ether, 2-methyl-2-butene + 2-methylbutan-2-ol, and diisopropyl ether + octane were collected at two temperatures using a modified Malanowski still. The vivial equation truncated at the second virial coefficient was used to calculate the vapor-phase fugacity coefficients. The liquid-phase activity coefficient data were fitted to the van Laar, Wilson, and NRTL equations.
