METHOD FOR PREPARING 4,4'-BIS-[4-AMINOFURAZAN-3-YL-N(O)N-AZOXY]-3,3'-AZOFURAZANE AND ITS APPLYING AS THERMOSTABLE EXPLOSIVE SUBSTANCE Russian patent published in 2005 - IPC

Abstract RU 2248354 C1

FIELD: organic chemistry, chemical technology, explosive substances.

SUBSTANCE: invention relates to a method for preparing 4,4'-bis-[4-aminofurazan-3-yl-N(O)N-azoxy]-3,3'-azofurazane of the general formula (1):

that is a new thermostable explosive substance with improved exploitation indices. Method for preparing compound of the formula (1) involves treatment of 4,4'-diaminoazoxyfurazane with potassium bromate solution (KBrO₃) in hydrochloric acid medium or its mixture with organic acid. Proposed compound can be used as a component of explosive compositions, solid rocket fuels and power-consuming compositions of different designations exploited at elevated temperatures (for example, in blast-hole drilling in depth mines).

EFFECT: improved preparing method, valuable properties of substance.
