Process for producing hydrogen peroxide

Methode de preparation de peroxyde d'hydrogene

Abstract

Abstract of the Disclosure The present invention provides a process for producing hydrogen peroxide by reacting oxygen and hydro-gen in a reaction medium catalytically using, as a cata-lyst, a tin-modified platinum group metal supported on a carrier. In the process using said catalyst, the pre-sence of halogen ion and acid in reaction medium is unnecessary unlike in conventional processes, and hydro-gen peroxide of high concentration can be produced effi-ciently. Thus, the present process has no restriction for reactor material as seen in conventional processes and further allows for easy purification of produced hydrogen peroxide.
