| titleOfInvention | Process for producing hydrogen peroxide |
| abstract | An aqueous hydrogen peroxide extract which contains small amounts of dispersed working solution and a working solution which contains small amounts of dispersed aqueous hydrogen peroxide are collected in the extraction stage of the anthraquinone method for preparing hydrogen peroxide. In order to purify these solutions, the working solution is compounded with aqueous hydrogen peroxide or preferably with water and the hydrogen peroxide extract is compounded with an organic dissolving mixture, preferably a quinone dissolver, and the respective dispersed phase is separated out with the aid of coalescers in a separator unit. It is especially preferable to add 1-3% by volume water or 1-3% quinone dissolver before the coalescer stages and to use coalescers with a drop-enlarging design and filter layers consisting of thermally desized glass filament yarn. The after-purification in accordance with the method results in a hydrogen peroxide which is improved as regards carbon content and color index as well as in an increase in yield of hydrogen peroxide and in a working solution with constant rel. moisture. |
