Abstract
La presente invención generalmente se refiere a procesos para la recuperación de rodio de una corriente de purga de catalizador de un proceso de hidroformilación de olefinas C6 o superior. En una modalidad, el proceso comprende (a) tratar una corriente de purga líquida que contiene el catalizador del proceso de hidroformilación, en donde el catalizador comprende un metal precioso y un ligando organofosforado, con un oxidante en presencia de una fase acuosa líquida separada que comprende un ácido libre de haluros a una temperatura suficiente para efectuar la oxidación de la mayoría del ligando organofosforado contenido, en donde el ácido libre de haluros es un ácido orgánico C1-C6 o un ácido fosforoso; (b) recuperar la fase acuosa; (c) poner en contacto la fase acuosa con una fase orgánica separada mediante la mezcla de las dos fases bajo una atmósfera de gas de síntesis, en donde la fase orgánica separada comprende un ligando organofosforado hidrolizable e insoluble en agua y la olefina reciclada de un proceso de hidroformilación; y (d) separar la fase orgánica a reciclar de regreso a un proceso de hidroformilación.
