Dinitrogen Trioxide is a chemical compound which can be represented using the chemical symbol N 2 O 3. Most spacecraft now use MON instead of NTO; for example, the Space Shuttle reaction control system used MON3 (NTO containing 3% NO by weight). Additionally, NTO is often used with the addition of a small percentage of nitric oxide, which inhibits stress-corrosion cracking of titanium alloys, and in this form, propellant-grade NTO is referred to as mixed oxides of nitrogen (MON). Dinitrogen tetroxide could be regarded as two nitro groups (-NO2) bonded together. • N2O4 + H2O = HNO2 + HNO3 • 4 N2H2 + N2O4 = 5 N2 + 4 H2O ›› Dinitrogen Tetroxide molecular weight.
