Abstract:
The extractive separation for water solution of diethoxy methane ( DEM) and ethanol has been determined by using liquid- liquid equilibrium still. The effect of forced stirring speed and time, stand still time and equilibrium temperature on the components of the system in equilibrium is studied. The liquid- liquid composition and affecting factors such as stirring speed, etc. are correlated by using least square method. The most suitable external conditions have been optmized for the separation process, providing the basis for further industrial test.
