The present invention relates to a method for carrying out a gas-liquid reaction in a flow reactor 1 having several parallel reaction chambers 8 which are open in the flow direction. The space-time yield STY has an average ratio of the chamber width b to the slit width s exceeding 3 and the slit width s is 5 to 100 mm, preferably 5 to 50 mm, and s / b It can be increased by using a reactor having three or more chambers having a value of 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.n n n n Gas-liquid reaction, plate stack, anthraquinone, hydrogen peroxide, flow reactor, space-time yield (STY) |
