Activity coefficient data and their correlation for tributyl phosphate—hydrocarbon and uranyl nitrate tributyl phosphate complex—hydrocarbon solutions

Activity coefficient data for 20 binary and seven ternary systems composed of nC 6H 14, nC 7H 16, nC 8H 18, C 6H 6, cy-C 6H 12, CCl 4, CHCl 3, (C 4H 9) 3PO 4 and UO 2(NO 3) 2 · 2((C 4H 9) 3PO 4) have been measured at 25 °C by head-space gas chromatography. The results of correlation of the experimen...

Description
Summary:Activity coefficient data for 20 binary and seven ternary systems composed of nC 6H 14, nC 7H 16, nC 8H 18, C 6H 6, cy-C 6H 12, CCl 4, CHCl 3, (C 4H 9) 3PO 4 and UO 2(NO 3) 2 · 2((C 4H 9) 3PO 4) have been measured at 25 °C by head-space gas chromatography. The results of correlation of the experimental data with three thermodynamic models, the Scatchard-Hildebrand, NRTL and UNIQUAC models, are compared. All three models can be used to predict activity coefficient data for ternary systems by means of binary parameters.
