A modified UNIFAC model is used in the correlation and prediction of enthalpies of mixing. The model requires two interaction parameters per group pair and values for 172 such pairs are presented here. Excellent prediction results are obtained with typical errors, in the temperature range of 273°K to 400°K, below 15%. For systems containing cyclic compounds, somewhat poorer results may be encountered.
