What is The Phase Split Forced by Salts or Carbohydrates in Nonaqueous Systems about?

More than 2500 ternary systems containing binary nonaqueous solvents and a salt or carbohydrate were checked experimentally under ambient conditions to demonstrate the liquid-liquid phase split. The binary solvents consisted of one strongly polar component and another significantly less polar. Phase separation has been observed in more than 300 systems. These systems are direct analogues of the aqueous two-phase systems (ATPS) that have been extensively studied and found numerous applications. The obtained data were analyzed and some correlations were observed. Possibilities of creating the liquid-liquid miscibility gap depending on the solvents' polarity and the solute properties were discussed. This phenomenon most often occurs with binary solvents containing a strongly polar component, such as formamide, dimethyl sulfoxide, ethane-1,2-diol, or N-methylformamide. Carbohydrates have been found to be better liquid-liquid phase split inducers than salts. Among the latter, calcium and lithium chlorides, and sodium iodide turned out to be the most effective. A strict correspondence of the decreasing probability of creating a miscibility gap by different ions with the reversed Hofmeist
