Özet

Experimental liquid-liquid equilibria of water + acetic acid + dimethyl phthalate and water + acetic acid + diethyl phthalate systems were investigated at 293.16 +/- 0.20 K. The reliability of experimental tie-line data was ascertained through an Othmer-Tobias plot. Distribution coefficients and separation factors were evaluated over the immiscibility region. It is concluded that the high-boiling solvents dimethyl phthalate and diethyl phthalate are suitable separating agents for dilute aqueous acetic acid solutions.
