| 摘 要： | 采用液相色谱法,在87～95.3℃温度范围内,测定了RDX在2,4-二硝基苯甲醚(DNAN)与N-甲基-4-硝基苯胺(MNA)低共熔体系中的溶解度。优化了色谱分离条件:流动相甲醇/水=6/4(V/V),流速为1.0 mL.min-1;检测波长254 nm,进样量5.0μL。实验考察了不同粒径的RDX、平衡时间以及温度对溶解度的影响,在低共熔物体系DNAN/MNA中,建立了RDX溶解度-温度关系曲线。结果表明,RDX在共熔体系中溶解度范围为9.39～10.28 g,并随着体系温度的升高而增大。

| Abstract: | High performance liquid chromatography(HPLC) was employed to analysis the solubility of RDX in melting DNAN/MNA at the range of 87 ℃ to 95.3 ℃.The optimal chromatography conditions were as following: mobile phase is methanol/water=6/4(V/V),and flow rate 1.0 mL·min-1,and wavelength of detector 254 nm,and injection volume 5.0 μL.The influence of particle size,equilibration time and temperature programming on solubility was studied.Under the optimum condition,the curve of the solubility of RDX in DNAN/MNA as a function of temperature was built.Results show that the solubility of RDX increases with increasing of the temperature. |
