Abstract
- The dissolution properties of 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazaisowutrzitane (TEX) in N-methyl pyrrolidone (NMP) were studied with a RD496-2000 Calvet microcalorimeter at four different temperatures. The heat effects were measured for TEX in NMP. The molar enthalpies and the differential molar enthalpies for TEX in NMP were also obtained at the same time. The corresponding kinetic equations that describe the four dissolution processes are d α/d t = 10(1− α) ( T = 298.15 K), d α/d t = 10(1− α) ( T = 303.15 K), d α/d t = 10(1− α) ( T = 308.15 K), d α/d t = 10(1− α) ( T = 313.15 K), and respectively. The values of activation energy E and pre-exponential factor A for TEX in the dissolution process are 16.84 kJ mol and 10 s. [ABSTRACT FROM AUTHOR]
