Vapor−Liquid Equilibrium Data at 343 K and Excess Molar Enthalpy Data at 298 K for the Binary Systems of Ethanol + 2,4,4-Trimethyl-1-pentene and 2-Propanol + 2,4,4-Trimethyl-1-pentene

Abstract

Isothermal vapor−liquid equilibrium data were measured for two binary systems, ethanol + 2,4,4-trimethyl-1-pentene and 2-propanol + 2,4,4-trimethyl-1-pentene, at 343 K. The measurements were made with a circulation still. The composition of liquid and condensed vapor phase was determined with a gas chromatograph. Excess molar enthalpy data were measured for the same binary systems at 298 K. Both systems indicate positive deviations from Raoult's law and exhibit azeotropic behavior.
