Propylene oxidation to acrolein on copper oxide catalyst was optimized at 300/sup 0/C, a 3.5:1 propylene-oxygen ratio, and a slightly reduced cuprous oxide catalyst of 2.17:1 copper-oxygen ratio. Increasing feed concentrations of both propylene and oxygen (in nitrogen) increased both conversion and selectivity for acrolein. The optimum oxidation state of the catalyst was obtained by starting with completely reduced copper; other initial oxidation states gave steady-state catalysts with higher oxidation states. High oxygen concentrations caused sintering and cupric oxide whisker growth.
