Abstract
A process for the production of ethylphenol comprising the oxidation of diethylbenzene into diethylbenzene monohydroperoxide, withdrawing the reaction mixture, separating the unconverted diethylbenzene therefrom to obtain a hydroperoxide concentrate containing at least 40% of diethylbenzene monohydroperoxide, mixing said concentrate with a solvent selected from the group consisting of the lower molecular weight aliphatic alcohols and ketones, decomposing said hydroperoxide by intimate contact with a strong acid, hydrogenating the decomposition mixture and recovering ethylphenol from the hydrogenated mixture.
