The heat of fusion for DNNC (1,3,5,5‐tetranitrohexahydropyrimidine) and its DNNC‐d6 analogue compound have been determined using differential scanning calorimetry analysis. No significant difference in the DNNC and DNNC‐d6 heat of fusion values was detected at the 95 and 99 percent student t confidence levels. Melting points were also determined for the subject compounds using this analysis technique. These melting points are compared to literature values obtained by conventional methods.
