Determination of guaranteed storage terms for gunpowders is performed by formula: is the content of nitrosoDPA in gunpowder. Value K≤0.9 is considered to be the index of the satisfactory chemical resistance.;EFFECT: elaboration of a quantitative method of determining the content of effective SCS....
Lavoisier improved French gunpowder, and later chemists produced high explosives making possible engineering achievements and also formidable weapons. All these things were seen as benefits. National chemical societies, their academic and professional aspects sometimes in tension, were formed and enjoyed ...
