| titleOfInvention | Preparation of spheroidal 3-nitro-1,2,4-triazol-5-one |
| abstract | The present invention relates to a process for the preparation of spheroidal 3-nitro-1,2,4-triazol-5-one, which consists in successively dissolving the starting 3-nitro-1,2,4-triazol-5-one of any crystalline form in a hot solvent mixture , containing water, at least one organic solvent and a surfactant, crystallizing 3-nitro-1,2,4-triazol-5-one from this mixture by cooling it, and then separating the crystallized spheroidal 3-nitro-1,2,4- triazol-5-one from the remaining mixture, preferably by filtration. The use of a hot mixture of 3-nitro-1,2,4-triazol-5-one dissolving, containing the above-mentioned components and two-stage cooling - successively using a heat exchanger and a slow one - allows to obtain spheroidal crystals of 3-nitro-1,2,4 -triazol-5-one with low porosity and medium size in the range from 100 µm to 350 µm. |
