Abstract

A method is described for the preparation of solutions containing little or no water of tertiary alkyl hydroperoxides in inert solvents by dewatering with sulfuric acid, according to which one or more inert organic solvents are added to an aqueous solution as well as sulfuric acid in such amount and concentration that in the aqueous phase forming after the mixing followed by separation of the phases there is at least 49% of H.sub.2 SO.sub.4 and the water content in the organic phase amounts to no more than 2.5%.
