Abstract

Traditional propellants emit toxic gases such as carbon dioxide and hydrogen chloride during combustion which are harmful to the environment. This study established a synthetic process of a high nitrogen containing derivative of tetrazine, 3,3-Azobis(6-Amino-1,2,4,5-Tetrazine) (DAAT), which can be applied as solid fuels for a solution to environmental concerns. Also, this paper described the detailed process and the analytic results of properties, which were not mentioned in previous reports. The compound was characterized by NMR, IR spectroscopy, and thermal, impact, and friction stability were measured. In addition, the heats of formation (${\Delta}H_f$) and detonation properties (pressure and velocity) of DAAT were calculated using Gaussian 09 and EXPLO5 programs.

기존에 사용되고 있는 대부분의 추진물질들은 연소 시 이산화탄소, 염산가스 등의 환경유해 물질을 다량 발생시킨다. 본 연구에서는 이러한 문제점을 개선하기 위한 테트라진 계열의 저탄소 고질소 화합물인 DAAT의 합성공정을 확립하였다. 또한, 문헌에 빠져있는 구체적인 공정법 및 특성 분석 결과를 서술하였다. 그리고 분광분석(NMR, IR)을 통한 DAAT의 구조분석과 열, 충격, 마찰 안정성을 측정하였고, Gaussian 09와 EXPLO5를 이용하여 생성열과 폭발 특성(폭압, 폭속) 등을 계산하였다.
