Abstract

Dinitramide ($N(NO_2)_2$) salts are one of plausible oxidizing agents for a high efficient propellant. Guanidine dinitramide (GDN) is an organic salt improving its stability against moisture, so that enables massive production and long term storage. Several types of GDN (GDN-1,2,3,4,5) were synthesized using some types of starting materials such as guanidine acetate, chloride, carbonate, nitrate and sulfate. As a result of the experimental work, synthesized GDN from the carbonate salt appeared fairly pure relatively higher yield (99%) than the other samples. The absorption wave length of all prepared GDNs by FTIR were found at 3452, 3402, 3354, 3278, 3208, 1642, 1570, 1492, 1416, 1337, 1179 and $1000cm^{-1}$. DSC analysis found a thermal phase change at $130^{\circ}C$, and indicated exothermic reaction at about $150^{\circ}C$ to $160^{\circ}C$.

Dinitramide($N(NO_2)_2$)염 화합물은 현재 고체 산화제로 로켓추진제의 중요한 원료 물질 중 하나이며, 환경 및 인체에 독성이 적은 친환경 에너지물질로 알려져 군사적 목적 외에 다양한 가스발생제로서 사용되고 있다. 특히 무기염이 아닌 유기염인 Guanidine 염(GDN)은 수분에 대한 안정성이 향상되어 안정적 보관 및 제조가 가능하므로 고순도 물질의 대량 생산이 가능하다. GDN의 출발물질로 guanidine의 음이온 염인 acetate, chloride, carbonate, nitrate, sulfate를 사용하여, GDN(GDN-1,2,3,4,5)을 최대 99%의 수율로 합성하였고, 이들의 물성을 다양한 분석기기를 이용하여 평가하였다. 흡수파장은 3452, 3402, 3354, 3278, 3208, 1642, 1570, 1492, 1416, 1337, 1179, $1000cm^{-1}$이 공통적으로 관찰되었으며, 열적 특성 변화는 $130^{\circ}C$에서 일어나기 시작하며 $150^{\circ}C{\sim}160^{\circ}C$에서는 발열반응과 함께 물질의 변화가 관찰되었다.
