Abstract:
The liquid- liqu id equilibr ium da ta o f terna ry DEM-ethano-l g lycerin sy stem have been dete rm ined a t atm osphe ric pressure and different temperatu res o f 20, 40 and 60 e , the con juga te phase com po sitions and thereout the contribution curves o f th is ternary liqu id- liqu id equ ilibrium system have been obta ined. The exper imenta l data a re correlated by using UN IQUAC and NRTL m ode ls, and the mode l param eters of this system have been obta ined respective ly, and the se lec tiv ity coe ffic ients o f the ex tracted solven t to so lutes we re calcu lated. G lyce rin is va lida ted as a good so lv ent in ex trac ting DEM - ethanol liqu id- liquidly, and thus the necessary basic data has been prov ided for industry extracting dev ices
