UHPLC-QTOF-MS High Efficiency Eetectionof Impurities in a Typical CL-20 Synthesis Process
摘要
Abstract
Quickly and accurately detect and analyze the intermediates and impurities produced in the synthesis of Hexanitro-hexaazaisowurtzitane(CL-20),is important for controlling the purity or quality of CL-20,and ensuring its sensitivity and detona-tion performance.In this study,nuclear magnetic resonance(NMR)and ultra-high performance liquid chromatography-Quadrupole time-of-flight mass spectrometry(UHPLC-QTOF-MS)were used to rapidly and efficiently analyze the impurities in the typical synthesis process of CL-20.The results showed that the impurity in HBIW was 1,3-dibenzyl imidaz-ole,the impurity in tetraacetyl dibenzyl hexazepane(TADB)was low acylated triacetyl tribenzyl hexazepane(TATB),and the impurity in tetraacetyl hexazepane(TAIW)was incomplete TADB.The impurities in CL-20 were not fully nitrated monoacetyl pentanitrohexazazine(MPIW)and diacetyl tetranitrohexazazine(DATN).关键词
