✦ Synopsis

  1. The vapour phase oxidation of hexanc has been studied with two different compositions at two different temperatures and pressures. Styrene introduced in sntall amounts was [ound to have a strong znhzbiting effect on oxidation and this effect is proportional to the amount oJ styrene introduced. It appears that styrene affects the branching ]actor (i.e. the branching and breaking-down elementary steps). (2) By using styrene labelled on ~-carbon atoms, it was possible to establish that the inhibitor molecules also undergo oxidation during the reactton, and various aldehydes and carbon dioxide are lormed ]rom the :~-carbon atonz. From exper2n~ental data the rate o] carbon d~oxide formation was calculated and compared with the rate of carbon &oxide formation ]rom hexane. (3) Frown the quantitatiw, data it can bc assumed that there is a correlation between the inhibiting effect of styrene and its competitive oxidation.
