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.
A method for precipitating as particles 2,6-diamino-3,5-dinitropyrazine -1-oxide present in an acid medium, the medium comprising nitric acid or a nitrate salt or a mixture thereof, and at least one strong acid other than nitric acid, the method comprising adding the acid medium to an aqueous solution comprising a nitrate salt;
A method for synthesizing particles of 2,6-diamino-3,5-dinitropyrazine -1-oxide, comprising:
