Excess enthalpies of partially miscible system 4-methyl-2-pentanol and water were measured with LKB-2107 Flow Microcalorimeter at 293.15 K, 298.15 K, 303.15 K under normal pressure. The results obtained were fitted with Redlich-Kister equation.
The NRTL parameters correlated from the H~E data measured on rich alcohol region were used to predict the vapor-liquid equilibrium under normal pressure with mean deviations of vapor composition and bubble point of 0.02 mole fraction and 1.03 K from the values in literature respectively.
