Synthesis Improvement and Thermal Properties of Bis(2,2,2-Trinitroethyl)-Nitramine (BTNNA)
摘要
Abstract
After the synthesis of intermediate product bis(2,2,2-trinitroethyl)-amine(BTNA) with nitroform (NF) and hexamethylenetetramine(HA) as substrates, target compound bis(2,2,2-trinitroethyl)-nitramine(BTNNA) was obtained through a nitration process. With mixed nitric and sulfuric acid as nitrating agent, the yield of BTNNA reached 93. 6%. IR and NMR were utilized to characterize the structure of BTNNA. Besides, for the same amount of BTNA, key factors that affected the nitration process, including the mole ratio of mixed acid, reaction temperature, and reaction time, were investigated as well. Results show that the optimum reaction condition is when the mole ratio of concentrated sulfuric acid to fuming nitric acid of 1. 0︰1. 8 at 30 ℃ for 20 min. Thermal properties of BTNNA were also studied by differential scanning calorimetry ( DSC) and thermogravimetry-differential thermogravimetric ( TG-DTG) . The decomposition tempera-ture is determined to be 177. 4 ℃, indicating that BTNNA is an energetic explosive with good comprehensive performance.关键词
