| Abstract: | The VLE data for the binary systems of benzene DMF,benzene thiophene and thiophene DMF,the ternary system of benzene thiophene DMF and the quarternary system of benzene thiophene water DMF are correlated by UNIQUAC,NRTL and McCann equations and the LLE data are correlated by UNIQUAC and NRTL equations.The ternary system is predicted by the three equations.The correlated precision meets the requirements of chemical engineering's design. |
