ABSTRACT
Liquid-liquid equilibria (LLE) in ternary mixtures of water + dipotassium oxalate + alcohol (2-propanol, 1-propanol, 2-methyl-2-propanol, and 2-butanol) have been studied at 298.15 K and atmospheric pressure. The experimental binodal and tie line data were determined at 298.15 K. The binodal curves were correlated using a three-parameter equation, and tie lines were satisfactorily correlated using the Othmer-Tobias, Bancroft, and modified Setschenow equations. The phase separation abilities of the investigated alcohols are in the order of 2-butanol greater than 2-methyl-2-propanol greater than 1-propanol greater than 2-propanol. The effect of temperature on the cloud points as a function of alcohol mole fraction has been studied at temperature range (293.15 to 328.15) K at 5 K intervals. The results show that the lower alcohol concentration is required for phase separation at higher temperatures.
