Abstract

Tri-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 \(\delta_{ij(i \ne j)}^{o}\) and local mole fractions \(x_{ij(i \ne j)}\) at 298.15 K were also estimated and reported.

磷酸三异戊酯和正十二烷的二元溶液在 283.15-363.15 K 温度范围内的密度和摩尔体积

自 1956 年以来，磷酸三丁酯（TBP）一直是基于 PUREX 的核循环操作的主力。然而，由于其相关的缺点，如第三相的形成以及在高温下与硝酸发生剧烈反应的倾向，PUREX 工艺需要一种替代萃取剂。磷酸三异戊酯（TiAP）在这两方面都比 TBP 具有更好的特性。溶液密度是设备设计、工艺操作、控制和安全分析的重要工艺参数。本研究报告了磷酸三异戊酯和正十二烷二元溶液在不同温度下的密度实验数据。还根据实验数据和 Kirkwood-Buff 积分估算了相关的体积参数。还估算并报告了 298.15 K 时的线性优先溶解系数（\delta_{ij(i\ne j)}^{o}\）和局部摩尔分数（\(x_{ij(i\ne j)}\）等衍生参数。

期刊介绍： International Journal of Thermophysics serves as an international medium for the publication of papers in thermophysics, assisting both generators and users of thermophysical properties data. This distinguished journal publishes both experimental and theoretical papers on thermophysical properties of matter in the liquid, gaseous, and solid states (including soft matter, biofluids, and nano- and bio-materials), on instrumentation and techniques leading to their measurement, and on computer studies of model and related systems. Studies in all ranges of temperature, pressure, wavelength, and other relevant variables are included.
