Activity coefficients of aqueous solutions of aceto-hydroxamic acid solutions at 298.15Â K and 0.1Â MPa

► Aceto-hydroxamic acid (AHA) is a novel reductant and complexant for actinides. ► Information on the thermodynamic parameters for AHA-water system is scarce. ► Few thermodynamic properties of aqueous AHA solutions are reported in this paper. ► An excellent agreement between predicted and experimental aw was observed. ► These are the literature first values to best of our knowledge.
