| titleOfInvention | High-selectivity and high-yield non-solvent preparation method of 1-methyl-3,4,5-trinitropyrazole (MTNP) intermediate 3,5-dinitropyrazole |
| abstract | The invention provides a high-selectivity and high-yield non-solvent preparation method of a high-energy insensitive explosive 1-methyl-3,4,5-trinitropyrazole (MTNP) intermediate 3,5-dinitropyrazole. The synthesis method comprises the steps: with pyrazole as a starting material, carrying out nitrification to introduce N-NO2 to a 1 site, and carrying out non-solvent rearrangement reaction translocation to a 3 site to generate C-NO2; then introducing N-NO2 into the 1 site, carrying out non-solvent rearrangement reaction translocation to a 5 site to generate C-NO2, to obtain the intermediate 3,5-dinitropyrazole, and carrying out nitration and methylation to obtain MTNP which is an ideal candidate for substitution of TNT. The synthesis method is simple, high in selectivity and high in yield, the used non-solvent rearrangement method is an important way for solving environmental pollution, the use of some high-toxic organic solvents is avoided, the cost is reduced, the problem of tedious post-processing is solved, and the requirements of green chemistry are met. |
