Abstract

AbstractTri-n-butyl phosphate (TBP) has remained workhorse of PUREX based nuclear recycle operations since 1956. However due to its associated disadvantages like third phase formation and tendency to react violently with nitric acid at elevated temperatures generated requirement of an alternate extractant for PUREX process. Tri-iso-amyl phosphate (TiAP) has better attributes than TBP on both the counts. Density of solutions is an important process parameter for design of equipment, process operations and control and safety analysis. In this work, experimental data on the density of binary solution of tri-iso amyl phosphate and n-dodecane are reported for several temperature levels. The related volumetric parameters were also estimated from experimental data as well as Kirkwood–Buff integrals. Derivative parameters like linear coefficients of preferential solvation $$\delta_{ij(i \ne j)}^{o}$$ δ i j ( i j ) o and local mole fractions $$x_{ij(i \ne j)}$$ x i j ( i j ) at 298.15 K were also estimated and reported.
