The modified S ´wie ¸tosławski ebulliometer was used for the accurate determination of vapor-liquid equilibria in binary isothermal systems formed by cyclohexane with: 2-butanol at 313.

The modified Świȩtosławski ebulliometer was used for the accurate determination of vapor−liquid equilibria in binary isothermal systems formed by n-hexane with the following: 2-butanol at (313.15, 323.15, and 333.15) K, 2-pentanol at (313.15, 323.15, 333.15, and 338.15) K, and 2-methyl-2-butanol at (313.15, 323.15, 333.15, and 338.15) K. The vapor pressures of the pure substances are also given. The experimental data have been compared with literature data (if available) of those systems and correlated by means of the Redlich−Kister, nonrandom two-liquid (NRTL), and Wilson equations.
