Aryldialkylmethanes such as cumene are converted to the corresponding hydroperoxides by reaction with oxygen in the presence of a promoter which may be an alkali metal borate such as borax, an alkali metal salt of a polymer such as an acrylic polymer, or an alkaline reagent in combination with a specific proportion of added water or water of hydration, also exemplified by borax. High yields of the hydroperoxide are obtained, particularly when the promoter includes water.

Method for preparing hydroperoxides by oxygenation

This invention provides a process for the manufacture of N-acetyl amino phenol, which process comprises reacting an appropriate phenol and an amide in the presence of a heteropoly acid or its alkali metal salt catalyst.

Process for the preparation of N-acetyl aminophenols

This invention relates to an improved process for the single step oxidation of 3-phenoxytoluene to 3-phenoxybenzaldehyde using molecular oxygen as the oxidant by employing a Ti.sub.2 VMoP.sub.6 O.sub.24 catalyst having particular infrared spectral bands.
