Abstract
The present invention relates to a method for purifying a mixture containing at least one alkyl hydroperoxide, preferably tert-butyl hydroperoxide or tert-amyl hydroperoxide, and at least one corresponding dialkyl hydroperoxide, said method comprising at least one step of extraction with water and at least one separation step which is carried out within the aqueous phase, obtained following the extraction step, in order to recover an aqueous solution which is rich in alkyl hydroperoxide. The invention also relates to an aqueous composition which is rich in alkyl hydroperoxide and contains at least 0.1% by weight of dialkyl peroxide in relation to the total weight of the composition.
