Isothermal vapor-liquid equilibria at 343.15 K for 2,2,4-trimethylpentane + 1,2-dichloroethane, + 1,1,1-trichloroethane, + 1,1,2,2-tetrachloroethane, + trichloroethylene, and + tetrachloroethylene binary systems have been determined using a recirculating still. The data were correlated by means of the Redlich-Kister equation. The excess Gibbs energies, determined from the vapor-liquid equilibrium data, present positive trends for all systems, with the maximum varying from 150 to 600 J mol(-1).
