This paper reports the method of synthesizing 2,4,6 trinitro 2,4,6 triazacyclohexanone (Keto RDX) from DPT (or PHX) and urea (or nitrourea) in several kinds of nitrating agents. There are primary investigations on reaction forms of nitrolysis fragments of DPT, PHX and BSX, and on the mechanism of forming by products. Experimental results showed that the nitrolysis fragments N,N dihydroxymethylamines that were not directly substituted by nitro groups condensed with urea or nitrourea to form Keto RDX, while N, N dihydroxymethylnitroamine did not. Using DPT as a reactant, the yield of Keto RDX was 69% (one mole Keto RDX per mol reactant), and by products were HMX, RDX and small molecule fragments. Using PHX, the yield was 36%, and by products were HMX and small molecule fragments. While using BSX, no Keto RDX product and no cyclonitroamine by products were obtained.
