Parameters of the bender equation of state for chloro derivatives of methane and chlorobenzene

Values of adjustable parameters of the Bender equation of state evaluated f or chloromethane, dichloromethane, trichloromethane, tetrachloromethane, an d chlorobenzene from published experimental data are presented. Experimenta l data employed in the evaluation included the data on state behaviour (p-r ho -T) of fluid phases, vapour-liquid equilibrium data (saturated vapour pr essures and orthobaric densities), second virial coefficients, and the coor dinates of the gas-liquid critical point. The description of second virial coefficient by the equation of state is examined.
