More Information
Summary:The process for the production of hydroxy aromatic substances by means of catalytic oxidation of isoalkyl aromatic substance with oxygen, and decomposition of the hydroperoxide thus formed, is based on the concept that isoalkylaromatic substances are emulsified with an aqueous catalyst solution and brought to a temperature ranging from 50 DEG C. up to the boiling temperature of the emulsion; thereupon the oxygen is allowed to act for 2 to 20 hours and the hydroperoxide formed decomposed, in the presence of an inorganic acid as catalyst, into an hydroxyaromatic substance and a ketone.
