摘要：

An experimental apparatus based on a flow method was used to measure the liquid-liquid equilibria for three ternary systems: water + hexane + hexadecane at 573 K and 20 MPa, water + toluene + decane at 553 and 573 K and 20 MPa, and water + toluene + ethylbenzene at 553 K and 20 MPa. Furthermore, the phase equilibria for water + toluene + decane and water + toluene + ethylbenzene were predicted by the modified SRK equation of state. An exponent-type and conventional mixing rules were applied for the energy and size parameters of the equation of state, respectively. The predicted results are in good agreement with the experimental results.
