Abstract: The invention relates to a device for carrying out, in a substantially isothermal manner, a heterogeneously catalysed reaction in a gas phase with high heat tonality. The inventive device comprises at least one reactor chamber (101) with an inlet (131, 141) and an outlet (143). The reactor chamber is defined by heat dissipating walls, lying at a substantially constant distance of /m and good thermal conductibility; the reaction gas in the reactor chamber flows at a rate of >/= 200 m per m surface area per hour; and a heat exchange medium flows on the side of the reactor wall opposite the reactor chamber.
