Binary Mutual Solubility Determination for Toluene-Tetraethylene Glycol (TETRA) with Water and Its Prediction by UNIFAC Group Contribution Model

摘要

Binary mutual solubility was measured for 3 systems, Toluene-TETRA, Toluene-TETRA+3%vater and toluene-TETRA+5%vvater, at the temperature rangeing from 293K to 383K. A new group was introduced into UNIFAC group contribution model, and the interaction parameters of the model were evaluated. The result demonstrated that the model can be used to predicte the binary mutual solubility of experimental systems with the dervation of 4.6%.
