The mechanism of promoting the autoignition of rich methanol–air mixtures by small additions of hydrogen peroxide has been studied using the tracer method. It has been shown that with the addition of hydrogen peroxide, the oxidation of methanol with atmospheric oxygen begins with the formation of hydroxyl from peroxide, followed by its interaction with methanol to form CH

. The branching factor for hydroxyl with the addition of peroxide is higher than without the addition of peroxide.
