Abstract

A catalytic process and a device for preparing, in absolute safely, aqueous hydrogen peroxide solutions at high concentration levels directly from hydrogen and oxygen; more particularly, a method whereby hydrogen and oxygen are injected, into the aqueous medium in proportions corresponding to the flammability range of the hydrogen-oxygen mixture, and are present in proportions outside the flammability range in the continuous gas phase. The invention also concerns a device for implementing the method.
