Differential Scanning Calorimeter (DSC) was used to investigate the thermal properties of 2,4-dichlorophenol+2,6-dichlorophenol and 2,4-dichlorophenol+2,3-dichlorophenol binary systems. The experimental results showed that The phase diagram of 2,4-dichlorophenol+2,6-dichlorophenol system was a simple eutectic type with the eutectic point at 294.99 K and 0.6200 mole fraction of 2,4dichlorophenol; The phase diagram of 2,4dichlorophenol+2,3dichlorophenol system was a simple eutectic type with the eutectic point at 291.86 K and 0.5834 mole fraction of 2,4dichlorophenol. Furthermore, the activity coefficients of components in mixtures of 2,4dichlorophenol+2,6dichlorophenol and2,4dichlorophenol+ 2,3dichlorophenol binary systems have been correlated by the Wilson model, respectively. |
