Abstract: Procedimiento para la obtención de fosgeno mediante reacción en fase gaseosa de monóxido de carbono y de cloro en presencia de un catalizador en lecho fijo, en uno o varios reactores (1) de forma cilíndrica, con un haz de tubos de contacto (2) dispuestos paralelamente entre sí, ordenados en la dirección longitudinal del reactor, que están fijados en sus extremos en platos de tubos (3), respectivamente con una caperuza (4) en ambos extremos del reactor (1), así como con chapas de desviación (6) dispuestas perpendicularmente con respecto a la dirección longitudinal del reactor, en cavidades intermedias (5) entre los tubos de contacto (2), que dejan libres, sobre la pared interna del reactor, orificios de paso (7) contrapuestos entre sí de manera alternativa, estando cargados los tubos de contacto (2) con el catalizador en lecho fijo, conduciéndose la mezcla de la reacción en estado gaseoso desde un extremo del reactor por una caperuza (4) a través de los tubos de contacto (2) y descargándosepor el extremo opuesto del reactor a través de una segunda caperuza (4) y conduciéndose a través de la cavidad intermedia (5) alrededor de los tubos de contacto (2) un agente intercambiador de calor líquido, caracterizado porque se dejan libres de tubos el o los reactores (1) en la zona de los orificios de paso (7) para la realización del procedimiento.

Abstract: A reactor (1) for preparing phosgene by gas-phase reaction of carbon monoxide and chlorine in the presence of a solid catalyst, which reactor has a bundle of parallel catalyst tubes (2) aligned in the longitudinal direction of the reactor whose ends are fixed in tube plates (3) and have a cap (4) at each end of the reactor (1), and has deflection plates (6) which are aligned perpendicular to the longitudinal direction of the reactor in the intermediate space (5) between the catalyst tubes (2) and leave free passages (7) located alternately opposite one another on the interior wall of the reactor, and in which the catalyst tubes (2) are charged with the solid catalyst, the gaseous reaction mixture is passed from one end of the reactor via one cap (4) through the catalyst tubes (2) and is taken off from the opposite end of the reactor (1) via the second cap (4) and a liquid heat transfer medium is passed through the intermediate space (5) around the catalyst tubes (2), where the reactor (1) has no tubes in the region of the passages (7), is proposed.
