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 (△difH) and molar enthalpies (△solH) 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.

Key words: Kinetics, Dissolution, Ethyl acetate, N,N-dimethylformamide, 1,3,3-Trinitroazetidine
