%X This paper reported the thermodynamics of extracting Re(VII) with the extractant of N8161 in the HCl system. The equilibrium molalities of ReO4- in the extraction: N8161(org)+H+(aq)+ReO4-(aq)=H+N8161ReO4-(org) were measured at ionic strength values from 0.1 to 2.0 mol/kg in the aqueous phase containing NH4Cl as the supporting electrolyte and at constant initial molality of extractant in the organic phase at the temperatures from 278.15 to 298.15 K. The standard equilibrium constant K0 at various temperatures was obtained, and the thermodynamic variations for the extraction process were calculated.
