摘要：
A simple vapor-liquid equilibrium (VLE) apparatus has been constructed to successfully measure the VLE of binary ethyl lactate systems that have relatively high differences in volatility (P-2(sat)/P-1(sat) similar to 7.0). Degassing is done in situ, reducing the experimental time considerably. Isothermal VLE of the ethyl lactate + ethanol system was measured at (40.0, 60.1, and 80.2)degrees C, and the isothermal VLE of the ethyl lactate + water system was measured at (40.0 and 60.0)degrees C. The ethyl lactate + ethanol system is slightly nonideal, and the ethyl lactate + water system forms a minimum boiling azeotrope. Isothermal data for ethanol + water were measured at 40.0 degrees C to demonstrate reliability of the apparatus.
