Methanol, ethanol, propanol are miscible with water. The alcohols with longer C-chains are not completely miscible. The solubility decreases the longer the C-chain.

If you add sufficient electrolyte, ethanol-water or propanol-water mixtures will separate into two phases.

I am not sure ― not clear from the enunciate ― if you could be interested in considering liquid-liquid extraction of the considered alchool from the aqueous phase to a nearly immiscible organic phase; for what it would be convenient to consider the solubility equilibrium diagram for the corresponding ternary system.  

The following discussion addresses the methanol―water―chloroform system:  https://www.researchgate.net/post/what_is_a_good_source_for_LLE_ternary_diagram_data_In_particular_I_am_looking_for_water-methanol-chloroform_data

Another case that you may want to consider, is when the alcohol is partially immiscible with water. In such a case, it may be found preferable to decrease the mutual solubility between both phases by cooling, and/or by adding a salt, preferably insoluble in the alcoholic phase but soluble in the aqueous phase. That also reduces the mutual solubility between both phases, due to what is known as the salting-out effect (*). This is the case for the phenol―water system, upon the addition of either potassium chloride or sodium chloride (**), which just dissolve noticeably in the aqueous phase. Note that phenol (as other phenols) are closely related to alcohols. Liquid-liquid phase separation becomes then possible, even without assistance of another solvent as extractant for the alcohol, as I have discussed at above post.

 Thank you Mr. Araújo Queiroz and Mr. John Miller for your valuable guidance. In fact, I want to extract a mixture of metals, dissolved in the aqueous phase, using solvent extraction system.
