Abstract

1490925 Hydrogen peroxide TOKUYAMA SODA KK 2 July 1975 27892/75 Heading ClA Hydrogen peroxide is prepared by direct reaction of hydrogen and oxygen in an aqueous medium containing a platinum-group catalyst (as defined) and wherein the partial pressures of hydrogen and oxygen in the gaseous phase of the reaction system (as defined) are at least 0À5 and at least 1À0 atmospheres respectively and the catalyst concentration is in the range of at least a minimum effective catalytic amount to 30 mg./100 ml. of aqueous phase, i.e. calculated as the metal. Preferably the ratio of the partial pressure of oxygen to hydrogen in the gas phase is from 1À5 : 1 to 20 : 1 and the catalyst is present in the amount 0À01 to 25 mg./ 100 ml. of aqueous phase. The catalyst may be used in the metallic form on a finely divided support, e.g. SiO 2 or Al 2 O 3 , or be utilized as a platinum group metal complex, e.g. phthalocyanine, dipyridyl, dimethylgloxime, as well as in salt forms.
