Abstract:Pyrazole and its derivatives are a kind of important nitrogen heterocyclic compounds, and have extensive application in many fields. Based on the reference literatures at home and abroad, this paper summarizes and compares the synthesis methods of 12 kinds of nitropyrazole compounds. Mainly, the research of such pyrazole series of low melting point compounds as 3,4-dinitro pyrazole (DNP) and 1-methyl-3,4,5-trinitropyrazole (MTNP), whose energy is higher than that of 2, 4, 6-trinitortoluence (TNT), and sensitivity is lower than that of TNT, is introduced. It could provide the basis for studying the further synthesis and performance of such energy materials. Their development is prospected, which could provide some new ideas for the further study of explosives with high density, high energy and low sensitivity, and of melt-cast explosive carriers which could take the place of TNT. These three aspects will be the research emphasis for a period in the future: explore the new synthetic route and process optimization of MTNP, study the physicochemical properties and the combination formulations with high energy compounds of the 3,4-DNP and MTNP, seek green nitration agents and catalyst needed in the synthesis of the nitro pyrazole compounds.
