Thermal Decomposition of Methanol in Shock Waves
J. Phys. Chem. 1989, 93, 7134.
Abstract
The thermal decomposition of methanol behind reflected shock waves with T5 from 1372 to 1842 K and C5 from 1.81E-5 to 2.15E-5 mol/cm3 was studied by IR laser kinetic absorption spectroscopy and gas-chromatographic analysis of reaction products. The absorption profiles and product yields were satisfactorily modeled with a 26-reaction mechanism. The initial rate of decrease of IR absorption intensity and the product yields were very sensitive to the rate constants of the reactions (-95), (A), (68), and (-56). The rate constant expression for the reaction (-56) was derived.
