| Abstract: | Melting temperatures have been measured and the solid liquid phase diagram was constructed for n butanol benzene.It is a simple eutectic system.Excess molar Gibbs free energies were calculated at 298 15 K,the largest value is 1 110 J/mol.The data were treated with Kretschmer Wiebe association model.The cross association constant K AB s have been calculated,the value of K AB for n butanol and benzene is 55 7 at 298 15 K. |
