Web8 mei 2014 · A detailed chemical kinetic mechanism for hypergolic ignition of N 2 H 4 in a N 2 O 4 - N O 2 gas mixture has been constructed. In this mechanism, the hypergolic ignition is mainly caused by the sequential reactions of H atom abstraction from N 2 H m … Web6 dec. 2012 · The MMH-NTO mixture has more reaction channels than EtOH-NTO based on statistical analyses of chemical reaction events and channels at early stages of the dynamics. Analyzing the evolution of product distribution over reaction time shows that the oxidizer (NO(2)) diffuses into the fuels (MMH or EtOH) for the occurrence of reactions, …
WebWe found that the major early chemical reactions between MMH and NTO are hydrogen abstractions and N–N bond scissions. The MMH–NTO mixture has more reaction channels than EtOH–NTO based on statistical analyses of chemical reaction events and … WebPyrophoricity is a special case of a hypergolic reaction because the oxidizing agent is restricted to atmospheric oxygen. Whereas pyrophoricity is concerned only with the spontaneous combustion of a material when exposed to air (atmospheric oxygen), a hypergolic reaction describes the ability of a material to spontaneously ignite or …
