A method for improving drastically both the selectivity and yield of hydrogen peroxide in the direct oxidation of hydrogen to hydrogen peroxide over a solid catalyst comprising palladium, which comprises:

Method for production of hydrogen peroxide with improved yield and selectivity by direct oxidation of hydrogen over palladium containing catalyst

The present invention discloses a process for the production of hydrogen peroxide from hydrazine hydrate or hydrazine salt, represented by a general formula:NH.nX,wherein, X is HO, HSO, HNO, HCl, HBr, HI or CHCOOH; n is 0.5, 1 or 2; N is nitrogen; H is hydrogen; S is sulfur; Cl is chlorine; Br is bromine; and I is iodine, by its liquid phase oxidation with oxygen, using a solid catalyst comprising palladium but with or without halogen promoter, in an aqueous reaction medium with or without comprising a mineral acid and/or halide anions, which comprises:

Process for preparing hydrogen peroxide

The present invention relates to a process for the liquid phase epoxidation of a normally liquid olefinic compound to corresponding organic epoxide compound using aqueous or anhydrous organic hydroperoxide as an oxidizing agent in the presence of a supported nano-gold catalysts at the effective organic hydroperoxide/olefinic compound mole ratio, catalyst/olefinic compound weight ratio and temperature to yield the epoxide.
