Abstract
La presente invención se refiere a procedimiento para la separación de yodo y sus compuestos a partir de los productos de carbonilación obtenidos carbonilando dimetileter, acetato de metilo o metanol, en presencia de catalizadores que contienen yodo, es decir los productos: ácido acético, acetanhidruro o diacetato de etilideno, en que para bajar la cantidad de yodo general que impurifica los productos de carbonilación a niveles menores a 20 ppb de yodo, se tratan los productos de carbonilación a temperaturas de 50 a 200 grados C con hidrógeno cuando menos en la presencia de un metal precioso del grupo VIII del Sistema Periódico de los Elementos en calidad de catalizador y se separan de este último, caracterizado porque se tratan los productos de carbonilación con mezclas de hidrógeno o monóxido de carbono.
