The transformation of 1,2-EPOXYBUTANE (cas 106-88-7) on PtCandPtCr2O3 catalysts in the presence of hydrogen has been studied in a flow apparatus at atmospheric pressure and in the temperature range 160–190 °C. Parallel formation of butanal, 2-butanone, 1-butanol, and 2-butanol has been observed. The selectivities of ring opening to 1- and 2-butane derivatives were independent of the reaction conditions but the ratio of isomerization to hydrogenolysis changed with the partial pressure of the epoxide and of hydrogen. Rate equations were found which satisfactorily described both reactions. The rate of isomerization depended also on the partial pressure of hydrogen, increasing linearly with it.
