分离并鉴定ＣＬ－２０制备中的副产物．方法利用柱层析对硝化粗品进行分离，得到了二乙酰基四硝基六氮杂异伍兹烷．结果与结论利用元素分析、ＦＴＩＲ、ＮＭＲ，ＦＤ－ＭＳ等手段对其结构进行了表征．
The by-products in the preparation of CL-20 were isolated and identified. Methods The crude nitrification products were separated by column chromatography to obtain diacetyl tetranitrohexaazaisowurtzitane. RESULTS AND CONCLUSIONS The structures were characterized by elemental analysis, FTIR, NMR and FD-MS.
