A series of laboratory and modelling experiments on the oxidation of propene in the gas phase has been undertaken to determine conditions which give high yields of propene oxide. The conditions under which the experiments were conducted were 505-549 K and up to 4 bar pressure. It is proposed that propene oxide is formed from propene by reaction with several peroxy radicals including hydroperoxyl and acetylperoxyl. However, one of the more important radicals is hydroxypropylperoxy. Its reaction with propene, under these conditions

        HOCH₂CHO₂CH₃  +  C₃H₆ = HOCH₂CHOCH₃  +  C₃H₆O            (107)

is more important than concerted decomposition to formaldehyde and acetaldehyde
