ABSTRACT
Phase diagrams for some alcohols + potassium or sodium citrate + water systems were measured at 25 deg C. The alcohols used are ethanol, 1-propanol, 2-propanol, 2-butanol, and 2-methyl-2-propanol. For these systems, binodal and tie line data were determined at 25 deg C. Binodal curves were described using a three-parameter equation. Tie lines were satisfactorily described using the Othmer and Tobias equations.
