Abstract

The purpose of this study is to separate nitrocellulose from 175 mm ammunition propellant by environmentally responsible recovery method. Recovery of nitrocellulose from obsolete ammunition is much more desirable than destruction since it can be reused in the several purpose. In spite of durable demilitarization of obsolete ammunition, the current holding amount of obsolete ammunition is gradually increasing and accumulated. The existing demilitarization methods, such as incineration and priming are strictly restricted for the noise, dust, oscillation and air and soil pollution. This study is focused on the separation of nitrocellulose by environmentally responsible recovery method by the solubility difference of nitrocellulose in nonpolar solvent. The purity of an extracted nitrocellulose was analysed by IR and TLC method and was clarified as very high.

본 연구는 175 mm 포탄추진체로부터 nitrocellulose의 친 환경적 분리에 관한 연구이다. 현재 국내외적으로 폐 탄약의 보유량은 점점 증가되고 있는 추세이며 부분적으로 비군사화가 시행되고 있으나 여전히 누적되고 있는 실정이다. 기존의 소각, 기폭 등의 재래식 방법은 소음, 분진, 진동을 동반한 오염물질 누출로 대기 및 토양오염을 초래하므로 제한을 받고 있다. 따라서 비극성 용매를 이용하여 nitrocellulose를 녹여내고 과량의 물을 가하여, 용해도 차이를 이용하여 고 순도의 nitrocellulose를 고형성분으로 추출하고, 추출된 nitrocellulose와 실험실에서 합성된 nitrocellulose를 IR 및 TLC 법으로 비교분석하여 추출된 물질의 순도를 확인한 결과 거의 순수한 nitrocellulose를 추출해 낼 수 있었다.
