Abstract
Dihydroperoxides of dialkylaromatic hydrocarbons are separated in high yield from an aqueous alkaline solutions of hydroperoxides containing the dihydroperoxides by adding 0.01 to 1 % by weight of a compound having a nitrogen base, such as ammonia and aromatic amines, to the solution, based on the weight of the solution, thereby stabilizing the dihydroperoxides in the solution, and separating the dihydroperoxides therefrom by extraction.
