| titleOfInvention | Method of preparation of 2,6-bis(picrylamino)-3,5-dinitropyridine |
| abstract | A method for preparing 2,6-bis(picrylamino)-3,5-dinitropyridine (PYX) which includes the steps of first dissolving crystalline PYX in a primary solvent in which the solvent used is selected from the group consisting of pyridine, dimethylformamide, methylsulfoxide or mixtures thereof. The primary solvent system is then combined with a second solvent in which the PYX is substantially insoluble, but which, in admixture with the primary solvent, forms a true solution of the PYX, referred to as the secondary solution. A third solvent is then added to the binary solvent system, which third solvent is soluble with the binary solvent system but which promotes precipitation of PYX in a form which exhibits improved characteristics as an explosive. |
