N2 - Henry's law constants of tetrachloroethylene, trichloroethylene, cis-dichloroethylene, and trans-dichloroethylene in air-aqueous alcohol systems were measured. Ethanol, 1-propanol, and 2-propanol were employed as cosolvents. Alcohol concentrations ranged from 0 to 20 vol %. Measurements were taken at temperatures from 0.2 to 70.0 °C. Using the experimental results, equations for the estimation of Henry's law constant as a function of both temperature and alcohol concentration were constructed. In addition, the Gibbs free energy (ΔdisG), enthalpy (ΔdisH), entropy (ΔdisS), and heat capacity change (ΔdisCp) associated with dissolution (solution to gas transfer) were derived by employing a linear regression analysis of the temperature dependence of the Henry's law constant.
