  • Cyclonite is a white powder and is very explosive. It can cause seizures (a problem of the nervous system) in human and animals when large amounts are inhaled or eaten. Research papers for workers exposure assesment of the cyclonite are very a few in the world. A field study was conducted at explosive compounds and bomb manufacturing companies to evaluate workers exposure to cyclonite. The airborne average concentration of cyclonite in explosive compounds manufacturing company was $4.10{\mu}g/m^3$(range: ND - $59.92{\mu}g/m^3$), and that of cyclonite in bomb manufacturing company was $31.49{\mu}g/m^3$(range: ND - $291.41{\mu}g/m^3$). Package process and assembly process in both companies were considered the high potential of exposure to cyclonite. Even though all airborne concentrations of cyclonite were lower than occupational exposure standard (MOEL: $500{\mu}g/m^3$), exposure to cyclonite can also occur through dermal contact during manufacture, handling, and clean-up of cyclonite. So control measures for protecting skin absorption of cyclonite were needed for preventing adverse health effect by cyclonite exposure.

  • 1,3,5,7-Tetranitro-1,3,5,7-tetraazacyclooctane (homocyclonite)의 합성에 있어서 부산물로 1,3,5-trinitro-1,3,5-triazacyclohexane (cyclonite)이 동시에 생성되는데, 본 연구는 반응메카니즘 측면에서 주 생성물 homocyclonite로 가는 중간생성물인 1,5-endomethylene-3,7-dinitro-1,3,5,7-tetraazacyclooctane (DPT)을 액체크로마토그래피로 추적하고 반응계내의 총 메틸렌대 아미노 N 비율을 결정하기 위해 반응중에 첨가되는 paraformaldehyde의 최적의 양을 찾기 위한 이론적인 식을 유도하였으며, (식 1 참조) 실제 실험에서 얻어진 결과와 비교함으로서 주생성물인 homocyclonite의 최대의 수율을 얻기 위한 반응조건을 확인하였다.

  • Eight representative explosives (ammonium perchlorate (AP), ammonium nitrate (AN), trinitrotoluene (TNT), 2,4-dinitrotoluene (DNT), cyclonite (RDX), cyclotetramethylenetetranitramine (HMX), pentaerythritol tetranitrate (PETN), and hexanitrostilbene (HNS)) were comprehensively analyzed with an ion trap mass spectrometer in negative ion mode using direct infusion electrospray ionization. MS/MS experiments were performed to generate fragment ions from the major parent ion of each explosive. Explosives in salt forms such as AP or AN provided cluster parent ions with their own anions. Explosives with an aromatic ring were observed as either $[M-H]^-$ for TNT and DNT or $[M]^{{\cdot}-}$ for HNS, while explosives without an aromatic ring such as RDX, HMX, and PETN were detected as an adduct ion with a formate anion, i.e., $[M+HCOO]^-$. These findings provide a guideline for the rapid and accurate detection of explosives once portable MS instruments become more readily available.
