Abstract
In the production of hydrogen peroxide by a process involving alternate reduction and reoxidation of an organic compound in a solvent medium, the hydrogen peroxide produced is extracted from the solvent medium by means of an aqueous solution containing an inorganic hydrogen peroxide stabilizer preferably in an amount of 0.01-0.5 gm/l. Organic compounds specified are 2-ethyl anthraquinone and phenazine. Stabilizers specified are alkali metal metaphosphate, pyrophosphate (e.g. normal sodium pyrophosphate and disodium dihydrogen pyrophosphate), and polyphosphate, aluminium phosphate, and sodium stannate. Ammonium nitrate may be present as corrosion inhibitor. In an example, a solution containing 90 gm/l. of 2-ethyl anthraquinone in a mixture of xylene and methyl cyclohexanyl acetate was subjected to reduction to produce the quinol in an amount corresponding to 3.0-3.5 gm/l. After reoxidation and extraction with water, a solution containing 150 gm/l. of hydrogen peroxide was obtained. Specification 465,070 is referred to.
