Synthesis of Ammonium Dinitramide by Nitration of Potassium and Ammonium Sulfamate. The Effect of Sulfamate Conterion on ADN Purity
Nitration of potassium sulphamate was carried out using a mixture of sulphuric and nitric acid at -30 °C. The reaction time was optimized at the mole ratio of sulphuric to nitric acid of (1:3.5). The difference in product yield by changing the potassium to ammonium sulphamate was studied throughly. It was found that both the yield and purity of the product is better starting with potassium ...
متن کاملMechanism and kinetics for ammonium dinitramide (ADN) sublimation: a first-principles study.
The mechanism for sublimation of NH(4)N(NO(2))(2) (ADN) has been investigated quantum-mechanically with generalized gradient approximation plane-wave density functional theory calculations; the solid surface is represented by a slab model and the periodic boundary conditions are applied. The calculated lattice constants for the bulk ADN, which were found to consist of NH(4)(+)[ON(O)NNO(2)](-) u...

متن کاملمطالعه اثر کاتالیستی اکسید روی )ІІ( (ZnO) با مورفولوژی متفاوت بر تجزیه حرارتی آمونیوم دی نیترآمید (ADN)
Ammonium dinitramide (ADN) with a positive oxygen balance (25.8%) is a metal free- energetic compound, which is used in military explosives and smokeless or green solid propellants. Combustion products of solid propellants based on ADN are clean and smokeless and they do not release hydrogen chloride gas, which can be an excellent alternative compound as an oxidizer in the solid propellant form...
متن کاملمرروری بر روش‌های تولید آمونیوم دی‌نیترآمید ((ADN و توسعه کاربردی آن در پیشرانش فضایی
Owing to the prime importance of ammonium dinitramide (ADN) as an oxidizer in solid propellants, its synthesis has received a great amount of interest. There have been several new and innovative synthesis routes developed by researcher’s worldwide. Liquid-fuel rockets consist of a fuel and oxygen (or other oxidizer) in liquid state. These fractals are already being combined together or combined...
