摘要： The invention concerns a process of continuously producing hydrogen peroxide by direct reaction between hydrogen and oxygen in a gaseous reaction mixture in contact with a catalyst maintained in a reactor (1), wherein a gaseous reaction mixture containing hydrogen and oxygen is supplied to the reactor through an inlet and hydrogen peroxide enriched gas (3) is withdrawn from the reactor through an outlet. According to the invention the temperature difference in the gaseous reaction mixture in contact with the catalyst between a position just after the inlet to the reactor and a position at the outlet of the reactor is maintained below about 40 DEG C.
