Chromatography Method For The Analysis Of Energetic Materials

Energetic materials have been extensively studied in many fields, and the analysis in the purity of energetic materials or content is the key process to control the synthesis Process.TAT and DPT is the most important intermediates for HMX, the most widely used energetic materials today, and the purification methods has been focused all along. In this paper the TAT molecularly imprinted polymer has been used as an online solid phase extraction column filler, and the acetonitrile were used as the solvent under the flow rate of 0.1 mL/min for 6 min, followed by the leaching solvent of ethylacetate for 0.9 min the changed to ACN for 12 min. After that using methanol for elution in 2 min and then the HILIC column has been used for the detection under the flow rate of 1mL/min by methanol. The detection conditions is under 215 nm wavelength UV for TAT, to achieve a rapid and automated separation and detection; methanol/water(10/90, v/v) has been used as the mobile phase under the flow rate of 1.0mL/min with 280 nm UV wavelength for the detection of DPT in different solvents. These two detection and data methods is the first time set up a program to provide courses for after work.DNAN is a kind of important cast explosive material, 2,2-nitroadamantane is a new energetic materials as the synthetic materials for polynitroadamantanes. This is the first time to use ion chromatographic methods to detect 2,2-nitroadamantane and DNAN in the sample for qualitative and quantitative analysis. 20 mM methane sulfonic acid(MSA) and 4.5 mmol/L Na2CO3 and 1.4 mmol/L NaHCO3 mixture solvent under the flow rate of 1.0 mL/min and 10 μL for injection to detect DNAN, we measured Cl-, NO3-, SO42-, Li+, Na+, NH4+, Mg2+, Ca2+ in the sample and the contents were 156.474, 21.654, 210.310, 13.234, 70.408, 15.327, 83.265, 154.158 μg/g; 20 mM methane sulfonic acid(MSA) and 4.5 mmol/L Na2CO3 and 1.4 mmol / L NaHCO3 mixture solvent under the flow rate of 1.2 mL/min and 10 μL for injection to detect 2,2-nitroadamantane, we measured CH3COO-, Cl-, NO3-, SO42-, Na+, NH4+, Mg2+, Ca2+ in the sample and the contents were 0.259, 0.215, 0.684, 0.423, 13.360, 105.600, 88.600, 367.700 μg/g.The TAT, DPT, DNAN and 2,2-nitroadamantane were researched as subjects in this paper by using high-performance liquid chromatography, two-dimensional liquid chromatography, ion chromatography, and mass spectrometry as detection methods, including the development and the establishment of four chromatographic analysis which can detect material compounds or separation, the data provided in the paper guiding the synthesis or purification method for the future course.
