ABSTRACT:
A process is provided whereby the hydrogen peroxide-containing oxidate from methyl benzyl alcohol oxidation is extracted with water and with ethyl benzene extractive solvent and an aqueous hydrogen peroxide phase is separated from an ethyl benzene solvent phase which also contains methyl benzyl alcohol and acetophenone, the improvement being that ethyl benzene is introduced into the extraction zone below the point of introduction of the oxidate, thus avoiding the possibility of formation of an aqueous hydrogen peroxide phase concentrated to a hazardous degree in hydrogen peroxide in the extraction zone.
