| 摘要 |
The present invention relates to a method for the production of hydrogen peroxide by hydrogenating a quinone solution (working solution), oxidation thereof and extraction of the oxidized working solution. The method is characterized in that the working solution which is to be hydrogenated consists of ethylanthraquinone in an amount of 140-170 grams/litre, preferably about 160 grams/litre, amylanthraquinone in an amount of up to 100 grams/litre, preferably about 40 grams/litre and the rest trimethylbenzen (Shellsol) and tetrabutylurea (TBU), octylcaprolactam or substituted pyrrholidones in a weight ratio of 65:35 to 70:30, preferably 70:30. The invention also comprises an arrangement for performing the method, which is characterized in that the separation arrangement (6) for separating the catalyst from hydrogenated working solution between the hydrogenating reactor and the oxidation tower includes a separator in the form of one or more hydrocyclones (13). |
