| abstract |
The present invention relates to a method for carrying out a gas-liquid reaction in a flow reactor (1) having several parallel reactor chambers (8) open in the flow direction. The space-time yield is at least three chambers in which the ratio of the chamber width (b) to the slot width (s) exceeds an average of 3, where the slot width (s) is 5 to 100 mm, preferably 5 to 50 mm, and s / b is 5 to 100). The flow reactor provided by the present invention comprising at least three chambers 8 and exhibiting the above ratio s / b is preferably tubular and contains at least one plate stack 5. The above method is suitable for the production of hydrogen peroxide according to the anthraquinone method, using a suspension-hydrogenation catalyst. |
