#xtrac #xtractio tion n of consti constitu tuent ents s by solve solvent nt is a very very common common practi practice ce in chemi chemical cal process processing ing where where a mixture mixture containing containing separabl separable e componen components ts is treated treated with a solvent in which one or more of the desired components are preferentially soluble. )sing a ternary plot and the gathered data from the earlier parts, we draw the boundary between two*phase and one*phase systems and the corresponding tie lines. efractive indexes were then recorded again for each layer. Water was then added to the mixture and the mixture was allowed to form separate layers. efractive indexes were then measured by a refractor and then recorded. #ach of them was then titrated with water (at $%&'! until permanent turbidity appeared. We crea create ted d four fourte teen en (1! (1! mixt mixtur ures es of buta butano noll and and acet acetic ic acid acid with with di"e di"errent ent compositions and then they were allowed to achieve thermal equilibrium. In this experiment, we used butanol, acetic acid and water as tertiary components.
But the addition of a highly polar substance demonstrates a change in its solubility. In most cases for liquids, two immiscible liquids cannot mix even with the addition of a tertiary component.
