Abstract: In the reactor for carrying out catalytic organic reactions in the gas phase, having reaction tubes (A) arranged between tube plates (B), the reaction tubes have an internal diameter in the range from 0.5 to 3 cm, the reaction tube length/internal diameter ratio is between 2 and 10, and a fluid heat transfer medium flows in the lateral direction around the reaction tubes (A). The tube bundle reactor is particularly suitable for exothermic organic reactions. … …
