摘　　要：采用饱和溶液-溶剂蒸发法在5、20、40和60℃条件下测试了平均粒度为80μm、5μm、500nm和100nm的HMX在不同溶剂中的溶解度。结合相似相溶原理和分子热运动分析了溶解度变化原因。结果表明,HMX在去离子水中基本不溶,在低级醇中的溶解度大于高级醇中的溶解度,在乙酸乙酯中的溶解度较大,随着温度升高,相同粒度HMX的溶解度增大;在同一温度下,随着粒度的减小,HMX溶解度增大。The solubilities of HMX with particle size of 80μm,5μm,500nm,100nm at different temperatures （5℃, 20℃,40℃,60℃）in different solvents were measured by evaporating the solvent in saturated solution.The reason of the solubility difference was discussed by similar dissolving principle and the thermal motion of molecules.The results show that the solubility of HMX in deionized water is almost zero,however it is larger in ethanol than that in trihydric and tetrahydric alcohol.With the increase of temperature,the solubility of HMX with the same particle size increases.Under the same temperature the solubility increases with the decrease of the particle size.
