摘要
Abstract
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 dissolu-tion enthalpies at 298.15,303.15,308.15 and 313.15 K are ΔdissH=60.17b-23.02b1'2+5.09,Δdiss H=62.17b-23.58b1/2+5.24,ΔdissH=65.45b-24.01 b1/2+5.37 and ΔdissH=68.57b-24.91 b1/2+5.60,respectively.The em-pirical formulate of the dissolution enthalpy of BuAENA dissolved in DMSO can be described as Δdiss H=(-53 080.91)/T+237.81 b+11 329.26/T-60.96b1/2+(-3 128.95)/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 dissolu-tion process are 3.35kJ/mol and 10-2.05s-1,respectively.关键词
