Abstract
In a tube bundle reactor for carrying out catalytic organic reactions in the gas phase, comprising reaction tubes (A) arranged between tubesheets (B), the reaction tubes have an inside diameter ranging from 0.5 to 3 cm, the ratio of reaction tube length to inside diameter ranges from 2 to 10, and the reaction tubes (A) are surrounded by a fluid heat transport medium flowing in the crosswise direction; said tube bundle reactor is useful in particular in exothermic organic reactions.
Claims10
A process for the preparation of an aliphatic, aromatic or araliphatic ketone and aldehyde by oxidative dehydrogenation of the corresponding alcohol in a strong exothermic reaction with a catalyst of group 1b of the periodic table which comprises passing the alcohol to be oxidatively dehydrogenated through the tubes of a short tube bundle reactor, which contains multiple reaction tubes (A) arranged between an enclosure of tubesheets (B), and passing a fluid heat transport medium through said enclosure crosswise across said tubes (A), such that the tubes are surrounded by the heat transport medium, said transport medium providing for removal of heat from the strong exothermic reaction such that the reaction is conducted significantly isothermally wherein the reaction tubes (A) have an inside diameter of from 0.5 to 3.0 cm and the ratio of reaction tube length to inside diameter ranges from 2 to 10.
