  • Precipitation method and synthesis method of 2,6-diamino-3,5-dinitropyrazine-1-oxide
    Patent number: 10836731
    Abstract: A method for precipitating as particles 2,6-diamino-3,5-dinitropyrazine-1-oxide (or ANPZO) present in an acid medium, which comprises adding the acid medium to an aqueous solution and which is characterized in that the aqueous solution comprises a nitrate salt. Further disclosed is a method for synthesizing ANPZO implementing this precipitation method. The synthesis method comprises converting 2,6-diaminopyrazine-1-oxide (or DAPO) into ANPZO by nitration in an acid medium, and then precipitating as particles the ANPZO by adding the acid medium to an aqueous solution, and is characterized in that the aqueous solution comprises a nitrate salt.
