Versuchsvorschrift

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 dispersion of 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 selected from the group consisting of acetone, methylethylketone and methylisobutyl ketone and an aromatic hydrocarbon selected from the group consisting of benzene, toluene, xylene and ethylbenzene containing 0.3 to 1.0% by weight of water based on the total starting mixture.
