Title:
PRECIPITATION METHOD AND SYNTHESIS METHOD OF 2,6-DIAMINO-3,5-DINITROPYRAZINE-1-OXIDE
Document Type and Number:
WIPO Patent Application WO/2018/158177
Kind Code:
A3
Abstract:
The invention is 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. The invention also 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. Applications: preparation of energetic materials.
