The enthalpies of solution of 2,4,6‐trinitro‐1,3,5‐trihydroxybenzene (trinitrophloroglucinol, TNPG) in N, N ‐dimethylformamide (DMF) and EtOH are determined. The thermodynamics of these processes are also studied. The experiments are carried out by a SETARAM C80 calorimeter at 298.15 K. The empirical formulas for enthalpies of solution of TNPG in both DMF and EtOH are calculated by polynomial expressions. The resulting formulas are: $\rm{\Delta _{{\rm{sol}}} H = - 97.23375 + 1646.78192b^{{1 \mathord{\bigg/ {\vphantom {1 2}} \kern-\nulldelimiterspace} 2}} - 6903.38866b}$ (in DMF), and $\rm{\Delta _{{\rm{sol}}} H = 93.19133 - 1731.03621b^{{1 \mathord{\bigg/ {\vphantom {1 2}} \kern-\nulldelimiterspace} 2}} + 8016.6928b}$ (in EtOH).
