4, 10- Dinitro-2, 6, 8, 12- tetraoxa-4, 10- diazaisowurtzitane (TEX) is well known as an efficient Insensitive high explosive. It was usually prepared via nitration of 1, 4- diformyl- 2, 3, 5, 6- tetrahydroxy piperazine reaction using a mixture of fuming nitricacid and concentrated sulfuric acid. However, these traditional liquid acids are toxic, corrosive and produce hazardous waste. In addition, these acidic mixture cause product decomposition and low yields despite their high catalyst activity. In this research the use of an efficient catalyst and mild reaction condition for TEX synthesis is reported for the first time. To access the high yields of ionic liquids, the ionic liquid, the amount of nitric acid, reaction temperature and reaction time have been studied. TEX was characterized by nuclear magnetic resonance spectra (NMR) and Fourier transform infrared (FTIR).
