摘要：

Isobaric and isothermal vapor-liquid equilibria were measured for the 2-methyl-1-propanol + octane system at a pressure of 101.3 kPa and a temperature of 373.15 K. The measurements were made in an equilibrium still with circulation of both the vapor and liquid phases. The 2-methyl-1-propanol + octane system forms a minimum boiling azeotrope or maximum pressure azeotrope. The azeotropic data are x(1)(AZ) = 0.670 and T(AZ) = 376.58 K for the isobaric and x(1)(AZ) = 0.654 and P(AZ) = 90.67 kPa for the isothermal system. The activity coefficients of the system were best correlated with the nonrandom two-liquid (NRTL) equation for the isobaric and with the Wilson equation for the isothermal system.
