ABSTRACT:
A process for producing 1,3-di-(2-hydroperoxy-2-propyl)benzene comprising an oxidizing step, an extracting step with an aqueous solution and a recycling step wherein the accumulated equilibrium concentration of 1,3-di-(2-hydroxy-2-propyl)benzene in the circulating oil obtained by an extracting step with an aqueous solution is 4.2% by weight or less. The process enables to avoid inconveniences like occlusion of inside space of an apparatus and failure of detection of measuring machines and allows continuous safe operation.
