Vapor-liquid equilibrium data at 343 K and excess molar enthalpy data at 298 K for the binary systems of ethanol plus 2,4,4-trimethyl-1-pentene and 2-propanol plus 2,4,4-trimethyl-1-pentene

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.
