摘要：
Pure component vapor pressure between (324 and 374) K, isothermal vapor-liquid equilibria at 358 K, excess enthalpy, excess volume, and density at 298 K were determined for three binary systems consisting of 2-ethoxy-2-methylbutane + 1-butanol, + 2-butanol, or + 2-methyl-2-butanol. Excess enthalpy was measured with a microflow calorimeter and excess volume with a vibrating-tube densimeter. A recirculation still was used to measure both the pure component vapor pressures and the phase equilibria of binary systems. The measured data were well-represented with local composition models. A maximum pressure azeotrope was observed for all measured systems.
