Abstract
Un procedimiento para la produccion de aldehído que tienen desde 3 hasta 21 átomos de carbono por hidroformilacion de las correspondientes olefinas con catalizadores de rodio, en el cual la descarga del reactor de hidroformilacion a) se separa en una fase gaseosa y una fase líquida, b) la fase líquida se separa en una fraccion de cabeza que contiene olefinas sin reaccionar y aldehidos, y una fraccion de cola que contiene el catalizador de rodio, y c) la fraccion de cola se enfría por debajo de la temperatura de la descarga del reactor de hidroformilacion y se inyecta un gas que contiene monoxido de carbono en la fraccion de cola.
