Process for making hydrogen peroxide.

摘要

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