Isothermal vapor‐liquid equilibria were measured using a still with the aid of a computer for control of the temperature and measurement of the total pressure. The measurements were made with circulation of both the vapor and liquid phases in a still of the Rogalski and Malanowski type (1980). The isobaric vapor‐liquid equilibria were measured for the benzene + 2‐propanol system at 101.3 kPa in order to test the consistency of results obtained with this still. Isothermal vapor‐liquid equilibria were measured for the 2,3‐dimethylbutane + methanol system at 313.15 K. The experimental data were correlated with the Wilson (1964) equation.
