Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, 274693-26-4, Name is 2-(((3aR,4S,6R,6aS)-6-(7-(((1R,2S)-2-(3,4-Difluorophenyl)cyclopropyl)amino)-5-(propylthio)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-3-yl)-2,2-dimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl)oxy)ethanol, SMILES is CC1(C)O[C@]([C@H](N2N=NC3=C(N[C@H]4[C@H](C5=CC=C(F)C(F)=C5)C4)N=C(SCCC)N=C32)C[C@@H]6OCCO)([H])[C@]6([H])O1, belongs to pyrimidines compound. In a document, author is Sinditskii, Valery P., introduce the new discover, SDS of cas: 274693-26-4.
Thermal Decomposition of 1,3,5,5-Tetranitrohexahydro-Pyrimidine: A New Type of Autocatalysis that Persists at High Temperatures
The thermal stability of 1,3,5,5- tetranitrohexahydropyrimidine (TNDA) in liquid phase under isothermal conditions was studied. It was established that the TNDA decomposition (k(liq)=3.1 . 10(21).exp(-26865/T), E-a=223.4 kJ mol(-1)) is accompanied by strong autocatalysis (k(cat)=9.8 . 10(14).exp(-18056/T), E-a=150.2 kJ mol(-1)). The mechanism of autocatalysis was proposed. The essence of autocatalysis is the oxidation of TNDA by decomposition products, followed by the destruction of the molecule. An unusual feature of this autocatalysis is that, in contrast to autocatalysis of nitroesters, the process does not disappear at high temperatures, but rather determines the kinetics of heat release in the combustion wave. The surface temperature and combustion mechanism of TNDA were established through thermocouple studies. It was shown that the autocatalysis reaction at the surface temperature controls the burning rate.
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 274693-26-4 is helpful to your research. SDS of cas: 274693-26-4.
