摘要： The invention relates to a device (R) for producing phosgene by reacting chlorine and carbon monoxide in the presence of a fixed-bed catalyst, comprising a) a tube bundle, which is arranged inside a reactor jacket (4) and which has a plurality of reaction tubes (3), which are arranged substantially parallel to each other and which extend from a lower tube sheet (2) to an upper tube sheet (2), and b) a coolant space for a cooling fluid, which coolant space surrounds the reaction tubes (3) and is defined by the lower tube sheet (1), the upper tube sheet (2), and the reactor jacket (4), wherein the device is characterized in that the tube bundle is enclosed by an annular-space sheet (7), which defines an inner annular space (12) for the passage of the cooling fluid and which is arranged at a distance from both the lower tube sheet (1) and the upper tube sheet (2), wherein an outer annular space (13) for feeding liquid cooling fluid through is formed between the annular-space sheet (7) and the reactor jacket (4), which outer annular space is in fluid connection with the inner annular space (12). The invention further relates to a method for producing phosgene by means of such a device.
