In a article，once mentioned of 6639-87-8

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. Application of 6639-87-8

Focused microwave irradiation of a series of halogenated nitrogen heterocycles and different kinds of nucleophiles in the presence of a catalytic amount of indium trichloride leads to the efficient and completely regioselective generation of aromatic C-C and C-N bonds. The method is simple, rapid, general and inexpensive, and can be performed without the use of dried solvents. Most of the synthetized compounds are new and in many cases the work-up required only filtration. Furthermore, this is the first example of the use of a Lewis acid as a catalyst for heteroarylation, vinylation and amination reactions on pi-deficient heterocyclic substrates.
