초록

우수한 고에너지물질의 개발은 질소 함량이 높은 화합물을 합성하는 방향으로 진행되어 왔으며, 궁극적으로 폴리질소의 형태를 지향한다. 폴리질소의 한 가지인 cyclo-N5-가 합성되고 다양한 금속, 비금속 화합물의 형성 결과가 확인됨에 따라, 폴리질소 화합물의 활용 가능성이 주목받고 있다. 그러나 다양한 펜타졸 염화합물 합성의 시작물질인 NaN5의 알려진 합성조건이 매우 극단적이고, 정제방법이 복잡한 만큼, 향후 pentazolate 화합물의 활용성을 높이기 위해서는 합성 및 정제 공정의 개선이 필수적이다. 본 연구에서는 NaN5 정제 방법을 단순한 여과 방식만을 적용하였으며, 이를 기반으로 두 가지 비금속-펜타졸 염화합물을 성공적으로 합성하였다.

The development of excellent high-energy materials has progressed in the direction of synthesizing compounds with high nitrogen content, ultimately oriented toward the form of polynitrogen. As cyclo-N5-, a type of polynitrogen, is synthesized as sodium pentazolate(NaN5) and the results of various metal and non-metal compounds have been studied, the usage of polynitrogen compounds is attracting attention. However, since the known synthesis and purification method of NaN5 are very extreme and complicated, it is essential to improve the process in order to increase the utility of the pentazolate compounds in the future. In this study, only a simple filtration method was applied to purify the NaN5, and based on this, two non-metal pentazolate salt compounds were successfully synthesized.
