Evaluation of hydrodynamic suitability of N,N-didodecyl N′,N′-di-octyl diglycolamide: a potential candidate for minor actinide partitioning

An unsymmetrical diglycolamide namely N,N, didodecyl-N′,N′-dioctyl diglycolamide developed in our laboratory is evaluated for its hydrodynamic suitability by determining the changes in its physical properties such as density and viscosity as a function of temperature and compared with those of tri n-butyl phosphate and N,N,N′,N′-tetraoctyl diglycolamide. The effect of irradiation on density, viscosity and interfacial tension, up to a dose of 1000 kGy are also measured. In addition, the activation energy for the viscous flow (E vis) were obtained for these pure solvents and their binary mixtures with n-dodecane in the temperature range 20–65 °C using the Andrade’s equation.
