Abstract

N-butyl-N-nitroxyethylnitramine (Butyl-NENA) is a nitramine-based softener that is widely used in the formulation of Nitramine compounds, such as HMX and RDX (gas generator components in the airbag, etc. ). In this study, a new preferred method has been developed for the synthesis of Butyl-NENA, which is safe and economiccompared to the reported synthesis routs. In this Project, the electrochemical synthesis of dinitrogenpentoxide was carried out in two processes of constant electric current and potential. Afterwards, Butyl-NENAwas synthesised using 2-butyl aminoethanol as a precursor, and subsequently a solution obtained from the electrolysis. During the synthesis of Butyl-NENA, time, temperature, and molar ratio of the reactants were optimized. The results of the sequential syntheses showed that the suitable temperature of nitration, the reaction time, and the molar ratio of Alcohol to Dinitrogenpentoxidesolution were 35 ° C, 1 hour, and 1: 3 respectively. In this way, temperature control is easily possible. The factors affecting the synthesis were investigated using Regression Test Design method. The results showed that the factors including temperature, molar ratio, and the reaction time do not act independently, and accordingly, the effects of their interactions were calculated.
