Zum thermischen unimolekularen Zerfall von Methanol

The thermal unimolecular decomposition of methanol was investigated behind reflected shock waves in the temperature range 1600 to 2100 K, using argon as a diluent and monitoring CH3‐ and OH‐absorption signals. —Methanol decomposes in the main channel according to magnified image The reaction takes place in the fall off region when total densities are varied from 1.1 · 10‐6 to 5.6·10−6 5.6·10‐5 mol/cm3. Using the theory of unimolecular reactions the rate constants magnified image in the high pressure limit and magnified image in the low pressure limit could be obtained. A computer simulation of the decomposition of methanol and the consecutive reactions was carried out.
