Abstract
A process for producing oxidized organic chemical products such as propylene oxide from various organic chemical feedstocks utilizing as oxidant directly produced hydrogen peroxide (H O ) intermediate oxidizing agent. The hydrogen peroxide intermediate is directly produced from hydrogen and oxygen feeds plus a suitable solvent in a first catalytic reaction step utilizing an active supported phase-controlled noble metal catalyst at reaction conditions of 0-100° C. temperature and 300-3,000 psig pressure. An organic chemical feedstock such as propylene together with the hydrogen peroxide intermediate and solvent solution are fed into a second catalytic reactor maintained at 0-150° C. temperature and 15-1,500 psig pressure and oxidized to produce a desired crude oxidized organic product such as propylene oxide, which is purified by distillation steps and recovered from the solvent solution.
