Abstract

The enthalpies of dissolution for 1,3,3-trinitroazetidine (TNAZ) in ethyl acetate (EA) and N, N-dimethylformamide (DMF) were measured using a RD496-2000 Calvet Microcalorimeter at 298.15 K under atmospheric pressure. Differential enthalpies (△(subscript dif)H) and molar enthalpies (△(subscript sol)H) were determined for TNAZ in different solvents. The corresponding kinetic equations that describe the two dissolution processes are dα/dt=10^(-7.26)(1-α)^0.88 for the dissolution of TNAZ in ethyl acetate and dα/dt=10^(-7.21)(1-α)^0.66 for the dissolution of TNAZ in N, N-dimethylformamide.
