Abstract
The phase diagrams for the ternary systems H2O + 2-butanol + K2HPO4/KH2PO4 (pH = 7) and H2O + 2-butanol + Na2CO3 at 298.15 K were determined. Experimental binodals and tie lines for these systems are presented. The experimental results were correlated using an improved regular solution theory. The agreement between the correlation and experimental data is good.
