Abstract:
A process for the preparation of hydrogen peroxide comprising (a) hydrogenating a compound of formula I wherein R1 is selected from CH3, C2H5 and C6H5 and R2 is selected from the group consisting of H and CH3 provided that when R1 is C2H5 or C6H5, R2 is H, in the presence of a palladium catalyst to obtain a compound of formula II; and (b) contacting said compound of formula II so obtained wherein R1 is selected from CH3, C2H5 and C6H5 and R2 is selected from the group consisting of H and CH3 provided that when R1 is C2H5 or C6H5, R2 is H, with an oxidant selected from the group consisting of molecular oxygen, air and a mixture thereof, in a biphasic system selected from ethylacetate-water and chloroform-water systems to obtain hydrogen peroxide.
