Reaction of CH3 radicals with methanol in the range 525 ⩽T/K ⩽ 603

Abstract

We have used molecular modulation spectrometry and a simple kinetic analysis, to make the first direct measurements on the reaction of methyl radicals with methanol. Product studies using gas chromatography were also carried out to complement the kinetic measurements. The rate constants derived in the temperature range 525 ⩽T/K ⩽ 603 are described by k₅= 1.3 (+1.3/–0.6)× 10^–11 exp(–55.1 ± 3.3 kJ mol^–1/RT) cm³ molecule^–1 s^–1.
