【摘要】 研究了ＮＥＰＥ推进剂中可提取有机组分（ＨＭＸ，Ｃ２和ＮＧ＋ＢＴＩＮ）的分离和测定方法．试样用ＴＨＦ浸泡２４ｈ后，在５０℃搅拌５ｈ．提取液采用正相高效液相色谱（ＮＰＨＰＬＣ）分离、测定ＨＭＸ，Ｃ２和混合酯．ＨＭＸ，Ｃ２和ＮＧ＋ＢＴＴＮ测定的相对标准偏差分别为０．３１％，１．２０％和２．１９％．更多还原

【Abstract】 The separation and detemination of the extrctable organic components (HMX, C2 and NG+BTTN) in NEPE propellent are investigated. NEPE propellant samples were soaked in the purified THF for 24h; then, heat and stir the solution in 50℃ for 5 h. HMX, C2 and mixed Nitrate in the extract were separated and determined by NP-HPLC. The relative standard deviations of HMX, C2 and NG+BTTN are 0.31%, 1.20% and 2.19%, respetively.更多还原
