Versuchsvorschrift

In accordance with one preferred embodiment of the present invention, there is provided a process for the preparation of resorcin comprising contacting impure meta-diisopropylbenzene dihydroperoxide obtained by liquid phase air oxidation of meta-diisopropylbenzene and/or meta-diisopropylbenzene monohydroperoxide, with a synthetic silica-alumina catalyst having a silica content of 60 to 95% by weight and a specific surface area of at least 100 m2 /g, under refluxing conditions in a mixed solvent of a ketone and an aromatic hydrocarbon containing 0.3 to 1.0% by weight of water based on the total starting mixture.
