Method for oxidizing an organic compound containing at least one C-C double bond

A process for oxidizing an organic compound having at least one C—C double bond or a mixture of two or more thereof, comprising:

• (I) preparing a hydroperoxide,
• (II) reacting an organic compound having at least one C—C double bond or a mixture of two or more thereof with the hydroperoxide from (I) in the presence of a zeolite catalyst,
• (III) regenerating the at least partially deactivated zeolite catalyst used in (II), wherein the regeneration comprises at least the following steps in sequence comprising at least two stages:
• (a) heating the catalyst in a stream of inert gas to a temperature of at least 200° C.,
• (b) subsequently, adding oxygen or an oxygen-supplying substance, wherein the amount of oxygen or oxygen-supplying substance added to the inert gas is regulated in such a manner that the temperature during regeneration does not exceed about 800° C. and does not fall below about 400° C., and
• (IV) conducting the reaction of (II) using a zeolite catalyst containing the catalyst regenerated in (III).
