摘要：

(Liquid + liquid) equilibria data of the (water + 1-propanol + dimethyl carbonate) system at T = (293.15, 303.15, 308.15, and 313.15) K and (water + 1-propanol + diethyl carbonate) system at T = (293.15, 298.15, 303.15, 308.15, and 313.15) K were measured under ambient pressure. The experimental results were correlated with the modified and extended UNIQUAC models. The reliability of the experimental tie-line data was tested through the Othmer-Tobias correlation equation. Distribution coefficients of dimethyl carbonate and diethyl carbonate were calculated from the experimental tie-line data and drawn. The temperature influence on liquid-phase equilibria was studied.
