QUE SIGNIFIE DINITROGEN TETROXIDE EN ANGLAIS
Tétraxide de dinitrogène
Le tétroxyde d'azote, plus précisément le tétraxyde d'azote, est le composé chimique N2O4. C'est un réactif utile dans la synthèse chimique. Il forme un mélange à l'équilibre avec du dioxyde d'azote. Le tétraxyde de dinitrogène est un oxydant puissant qui est hypergolique au contact de diverses formes d'hydrazine, ce qui rend la paire un bipropellant populaire pour les roquettes.
définition de dinitrogen tetroxide dans le dictionnaire anglais
La définition du tétroxyde de diazote dans le dictionnaire est une substance gazeuse incolore qui existe en équilibre avec le dioxyde d'azote. Lorsque la température est réduite, la proportion de tétroxyde augmente. Formule: N2O4.
