ABSTRACT:
In a process for the catalytic oxidation of isoalkylaromatic hydrocarbons into ketones, alcohols and peroxides the isoalkyl- aromatic hydrocarbons in fluid phase at a temperature of 60 to 120.degree. C. are oxidized by oxygen in the presence of a catalyst of metal salt of different valency and alkylammonium salt or alkylphosphonium salt. Further there is claimed a catalyst for the oxidation of isoalkylaromatic hydrocarbons, containing a metal salt selected from copper salts, cobalt salts and manganese salts or their mixtures and an alkylammonium salt or alkylphosphonium salt in a ratio of metal salt to alkylammonium salt or alkylphosphonium salt of 0.5 to 50:1.
