Abstract
1. Procedimiento mejorado para preparar fosgeno, mediante reacción de cloro con monóxido de carbono en una zona de reacción, para producir un productor que comprende fosgeno y monóxido de carbono sin reaccionar, y separación de prácticamente la totalidad del fosgeno del monóxido de carbono sin reaccionar, caracterizado porque comprende reciclar al menos una porción del monóxido de carbono sin reaccionar a la zona de reacción, con lo cual se aumenta el rendimiento de materias primas del proceso y se reduce la cantidad de monóxido de carbono desechado como corriente residual.
