摘　　要：概述了同位素标记的奥克托今(HMX)及其前体化合物的合成方法,同位素示踪法在醋酐法、小分子法以及以乌洛托品为基的新法合成HMX合成反应机理研究中的应用,还介绍了使用同位素示踪法在生物降解过程中对降解产物的鉴定和定量作用。研究表明,在醋酐法制备HMX的过程中倾向于重组机理;然而在TAT法和DADN法制备HMX过程中更倾向于逐步降解机理。用标记的HMX-14C可以用于生物降解产物的准确定量和定性。The synthesis of isotope labeled cyclotetramethylenctetramine （HMX） and its precursor, and the application of isotope tracing technique in the synthesis of HMX by acetic anhydride method and non-acetlc anhydride method were summarized. The application of isotope tracing technology in the biodcgradation process of energetic contaminants were also introduced. The study shows that HMX prepared from the acetic anhydride method tends to restructuring mechanism; HMX prepared from the TAT and DADN method is more inclined to the step-by-step degradation mechanism. HMX-14C can be used for the quantitative and qualitative analysis of biological degradation products accurately.
