A process for making hydrogen peroxide by catalytically reacting oxygen with hydrogen in a liquid reaction medium, which comprises n (a) filling a reactor with a liquid reaction medium containing a catalyst, n (b) dissolving oxygen and hydrogen in the liquid reaction medium by contacting the gases separately and simultaneously with the liquid reaction medium in the reactor, n (c) thus forming hydrogen peroxide in the liquid reaction medium containing the catalyst, n (d) while maintaining the reactor at such condition that a gaseous phase containing a combination of both oxygen and hydrogen is substantially absent during the reaction, and n (e) separating the catalyst from the resulting reaction mixture containing hydrogen peroxide. |
