Binary phase diagram series: 1,3,3-trinitroazetidine (TNAZ)/N-acetyl-3,3-dinitroazetidine¹(ADNAZ)

Abstract Binary phase diagrams for the 1,3,3-trinitroazetidine (TNAZ)/N-Acetyl-3,3-dinitroazetidine (ADNAZ) system have been predicted computationally and determined experimentally. Physical mixtures exhibit the thermal characteristics associated with a simple binary eutectic system, while the behavior of fused mixtures is consistent with a simple linear solid solution system on the ADNAZ-rich side of the eutectic and a simple binary eutectic system on the TNAZ side. Experimental eutectic temperature/composition (°C/mol percent TNAZ) values for physical and fused mixtures are 75.4/63.8–64.9 and 74.2/61.7–64.0, respectively.
