NEW CHEMICAL COMPOUND SUITABLE FOR USE AS AN EXPLOSIVE, INTERMEDIATE AND METHOD FOR PREPARING THE COMPOUND

摘要

A new compound, 1,1-diamino-2,2-dinitroethylene suitable for use as an explosive, as well as an intermediate for preparing the compound consisting of a heterocyclic 5- or 6-ring of general formula (4) wherein n = at least 1. The compound is prepared by nitrating a heterocyclic 5- or 6-ring containing structural element (1) or (2) wherein Y is an alkoxy group, with a nitrating acid at a low temperature, preferably 0-30 DEG C, and selecting the acidity of the nitrating acid for obtaining a substantial yield of a product containing structural element (3) and hydrolysing said product in an aqueous medium for separating 1,1-diamino-2,2-dinitroethylene which is recovered as a precipitate.
