METHOD OF PRODUCING TETRAZENE Russian patent published in 2016 - IPC C06B49/00 C07D215/00

Abstract RU 2593636 C2

FIELD: blasting.

SUBSTANCE: invention relates to the technology of explosives and can be used to increase safety of production and use of standard explosive - tetrazene C₂H₈ON₁₀ (GNGT). When producing tetrazene from pre-heated solutions aminoguanidine sulphate and sodium nitrite, sodium nitrite solution is mixed with modifying additive, which is a mixed aqueous solution of dextrin and gelatin, and a special dosage aminoguanidine sulphate solution to solution of sodium nitrite. Loose tetrazene with sizes and shape of crystals, which provide it with improved processing properties, is obtained.

EFFECT: produced tetrazene has high bulk density of not less than 0 65/100 g/cm³ and relative scatter of weighed portions with volumetric measurement of 5 %.
