摘要：

The AMP/Pz system is industrially important but modeled VLE data are scarce. Reported data were used to develop a NRTL model representing binary VLE data of aqueous AMP and Pz solutions and ternary VLE data for aqueous AMP/Pz solutions at different temperatures and concentrations. The model represents very well the experimental results, but could be improved when more data are available in the parameter regression. The model shows that the activity coefficients of AMP are higher than those of Pz. The suggested binary interaction parameters can reasonably well predict the ternary system. (C) 2013 The Authors.
