Abstract
A process for removing and neutralizing mineral acid catalyst and organic acid byproducts from a reaction mixture resulting from the dissolution of cumene hydroperoxide, which method comprises contacting said reaction mixture at a temperature below 50 [deg.] c., in a first zone, with an aqueous solution comprising an inorganic salt and an excess of an alkali metal hydroxide or phenate sufficient to neutralize the mineral acid and the by-products of existing organic acids, and maintain the ph of the aqueous phase between 7 and 9, what these acids are extracted from the organic phase in the aqueous phase and neutralized there, separate the aqueous phase containing the neutralized acids, then put in contact, at a temperature between 10 and 60ºC approximately, the organic phase, in a second zone, with an aqueous solution comprising an inorganic salt and a weak acid, in sufficient quantity to decompose the alkali metal phenate transported from the first zone, and thereafter, separating said aqueous phase therefrom.
