Reference of 6639-87-8, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 6639-87-8, molcular formula is C8H5N3O2, introducing its new discovery.
Pressure Effects on the Thermal Decomposition of Nitramines, Nitrosamines, and Nitrate Esters
Solutions of nitramine and nitrate ester explosives and model compounds were thermolyzed at various hydrostatic pressures and their rates of decomposition were measured.The effects of pressure on their rates were used to infer the mechanism of their initial decomposition steps.Most nitramines, including the explosive octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), appear to undergo homolysis of the N-NO2 bond, because their reaction rates decrease with increasing pressure.Exceptions are hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) and the model compound, 6-nitro-1,2-dinitroso-1,2,3,4-tetrahydroquinoxaline, which react faster with increasing pressure.These two compounds can aromatize by elimination of HNO2 and HNO, respectively.Secondary nitrate esters shift their major decomposition pathway from homolysis of the O-NO2 bond to elimination of HNO3 in the pressure range of 0.4 to 0.8 GPa.The elimination reaction resembles carboxylate ester pyrolysis with E1 character.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 6639-87-8 is helpful to your research. Reference of 6639-87-8
