Analyses of New Nontoxic Stabilizers and Other Components in Smokeless Powders

Popis výsledku v původním jazyce

Propellants consisting of nitrocellulose and/or other nitric esters are inherently chemically unstable and undergo decomposition even under standard storage conditions. Decomposition of such compounds can be inhibited or nearly stopped when stabilizers are used. However, conventional stabilizers form nitrosamines that have toxic and carcinogenic effects. A nitrocellulose based propellants contained new nontoxic stabilizers were prepared on this account. The chemical structure of the new stabilizers andtheir decomposition products should prevent the formation of toxic N-nitrosamines. We prepared double base propellants and these powders were investigated using Microcalorimetry, Conventional Stability Tests and Sensitivity Tests. The results were compared with propellants containing the conventional stabilizer akardite II. Therefore, this paper presents qualitative and quantitative analyses results of the new substances as stabilizers for propellants.
