Utilization of New Non‐toxic Substances as Stabilizers for Nitrocellulose‐Based Propellants

Abstract: Propellants consisting of nitrocellulose (NC) and/or other nitrate 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. As a result, these conventional stabilizers should be replaced as soon as possible. A series of NC‐based propellants doped with different novel manufact… Show more

“…The successful attempts have also been made by other workers 9 , where heat of combustion of new energetic thermoplastic elastomers based on GAP, polyNIMMO and polyGLYN were carried out in Parr calorimetric oxygen bomb at 3 MPa to co-relate the energy output of the prepared composition. On the same line, the cal-val of new non-toxic substances as stabilizer for nitrocellulose based propellants were also reported 10 in vacuum of constant volume at a temperature of 25˚C and heat output were compared with conventional stabilizers.…”

“…Estas últimas geralmente contêm a nitrocelulose (NC) como principal componente de suas formulações, cuja instabilidade demanda a utilização de estabilizantes. 1 Os estabilizantes são substâncias utilizadas nas formulações de propelentes com a finalidade de retardar o processo de degradação natural da NC, prolongando o tempo de vida dos propelentes à base de NC, quando em condições adequadas de armazenamento. 1 No processo de interação química entre os estabilizantes e os vapores nitrosos oriundos da degradação da NC, é gerada uma grande variedade de compostos nitrosados, dentre os quais se destacam as N-nitroso-aminas e as N-nitroso-amidas.…”

Tais substâncias tóxicas são as principais responsáveis pelos riscos à saúde dos profissionais que manipulam pólvoras e propelentes, assim como, pela contaminação do ambiente.…”
