Abstract

The enthalpies of dissolution in ethyl acetate and acetone of hexanitrohexaazaisowurtzitane (CL-20) were measured by means of a RD496-2000 Calvet microcalorimeter at 298.15 K, respectively. Empirical formulae for the calculation of the enthalpy of dissolution (ΔdissH), relative partial molar enthalpy (ΔdissHpartial), relative apparent molar enthalpy (ΔdissHapparent), and the enthalpy of dilution (ΔdilH1,2) of each process were obtained from the experimental data of the enthalpy of dissolution of CL-20. The corresponding kinetic equations describing the two dissolution processes were for dissolution process of CL-20 in ethyl acetate, and for dissolution process of CL-20 in acetone.
