Abstract

Di-isopropyl benzene is oxidized to the mono-and di-hydroperoxides by treatment with oxygen-containing gases in the substantially homogeneous liquid phase between 110 DEG and 140 DEG C. in the substantial absence of oxidation catalysts other than organic peroxides. The starting material may be a pure isomer or a commercial mixture of the o-, m- and p-isomers, of which the preacts easily, the mless readily and the oto a very small extent only. The oxidizing gas may be pure oxygen or a mixture containing it, e.g. air, and the quantity of oxygen introduced is preferably in excess of that absorbed. Acidic by-products which p interfere with the reaction are neutralized by adding a small amount of an alkaline substance (e.g. sodium hydroxide), preferably in the form of an aqueous solution or suspension. The water thus added is quickly vaporized and helps to remove the acidic materials by entraining them, and at the same time the steam minimizes the risk of explosions in the gaseous phase. Extra water or steam may be added, provided the quantity is not sufficient to produce a separate liquid phase. The various products may be separated and purified by conversion into their alkali metal salts and subsequent hydrolysis, as in Specification 641,250. Examples are given.
