摘　　要：为研究丁基叠氮乙基硝胺(BuAENA)在二甲基亚砜(DMSO)中的溶解行为,建立了一种可以预测溶解焓的方法;采用C80微量热仪测定了BuAENA在常压条件、4种不同温度下溶解于DMSO中的溶解特性。结果表明,溶解过程为吸热,在298.15、303.15、308.15和313.15K温度下的溶解焓分别为Δ_(diss)H=60.17b-23.02b^(1/2)+5.09,Δ_(diss)H=62.17b-23.58b^(1/2)+5.24,Δ_(diss)H=65.45b-24.01b^(1/2)+5.37和dissH=68.57b-24.91b^(1/2)+5.60。BuAENA在DMSO中的溶解焓表达式可以描述为Δ_(diss)H=(-53080.91)/T+237.81b+11329.26/T-60.96b^(1/2)+(-3128.95)/T+15.57,并通过测量343.15K温度下的溶解焓验证了该表达式的准确性。溶解过程的动力学活化能和指前因子分别为3.35kJ/mol和10^(-2.05)s^(-1)。The dissolution behavior of N-butyl zaideethylnitramin(BuAENA)dissolved in DMSO(dimethyl sulfoxide)has been studied in the paper,and a method that can predict the dissolution enthalpy was also established.The dissolution properties of BuAENA in DMSO at four different temperatures under atmospheric pressure were measured by using a C80 microcalorimeter.The results show that the dissolution process for the BuAENA in DMSO is endothermic,and the empirical formulate of dissolution enthalpies at 298.15,303.15,308.15 and 313.15K areΔ_(diss)H=60.17b-23.02b^(1/2)+5.09,Δ_(diss)H=62.17b-23.58b^(1/2)+5.24,Δ_(diss)H=65.45b-24.01b^(1/2)+5.37 andΔ_(diss)H=68.57b-24.91b^(1/2)+5.60,respectively.The empirical formulate of the dissolution enthalpy of BuAENA dissolved in DMSO can be described asΔ_(diss)H=(-53080.91)/T+237.81b+11329.26/T-60.96b^(1/2)+(-3128.95)/T+15.57.And the accuracy is verified by measuring the dissolution enthalpy of the BuAENA in DMSO at 343.15K.The values of activation energy E and pre-exponential factor A for the dissolution process are 3.35kJ/mol and 10-2.05s-1,respectively.
