摘　　要：采用饱和溶液-溶剂蒸发法测试了平均粒径分别为20 m、5 m、500nm和100nm的黑索今(RDX)样品在乙酸乙酯、乙醇、正丙醇、异丙醇、正丁醇、仲丁醇、异丁醇和去离子水8种溶剂中,分别于5,20,40,60℃下的溶解度。结果表明,在相同的温度下,同种粒度级别的RDX在去离子水中的溶解度最小,在乙酸乙酯中的溶解度最大;在乙醇中的溶解度大于在丙醇和丁醇中的溶解度;在正丁醇中的溶解度大于在仲丁醇和异丁醇中的溶解度。在相同溶剂中,在同一温度下,随着粒度减小,RDX溶解度增大。随着温度升高,同种粒度级别的RDX的溶解度增大。The solubility of RDX with average particle size of 20 m,5 m,500 nm and 100 nm in the 8solvents including the ethyl acetate,ethanol,propyl alcohol,isopropanol,n-butyl alcohol,sec-butyl alcohol,isobutanol and deionized water at 5,20,40℃and 60℃ respectively were measured by the evaporation method of the solvent in the saturated solution.Results show that the solubility of RDX with the same granularity level is lowest in the deionized water and highest in the ethyl acetate.The solubility in ethanol is higher than that in propyl alcohol and butyl alcohol.The solubility in n-butyl alcohol is higher than that in sec-butyl alcohol and isobutanol.In same solvent,the solubility of RDX at the same temperature increases with decreasing of the particle size.The solubility of RDX with same granularity level increases with the increasing of temperature.
