| 摘 要： | 在常压、298.15 K条件下, 用RD496-2000微热量仪分别测量了1,3,3-三硝基氮杂环丁烷(TNAZ)在乙酸乙酯(EA)和N,N-二甲基甲酰胺(DMF)中的溶解焓. 得到了TNAZ在不同溶剂中的微分溶解热和积分溶解热. 建立了热量与溶质的量之间的关系式. 对TNAZ, 得到了在乙酸乙酯中描述溶解过程的动力学方程为dα/dt=10-7.26(1-α)0.88; 在N,N-二甲基甲酰胺中, 描述溶解过程的动力学方程为dα/dt=10-7.21(1-α)0.66.

| 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 298.15K under atmospheric pressure.Differential enthalpies(△_(dif)H)and molar enthalpies(△_(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. |
