In this work experimental vapor pressures of hexahydro‐1,3,5‐trinitro‐1,3,5‐triazine (RDX) and hexahydro‐1,3,5‐trinitroso‐1,3,5‐triazine (TNX) were measured with transpiration method. Corresponding enthalpies of sublimation were determined to be (130.9±2.1) kJ mol −1 and (108.1±1.6) kJ mol −1 , respectively. Along with the experimental data fitting equations are reported and p‐T data extrapolated to 298.15 K to be 0.71 μPa for RDX and 823 μPa for TNX.
