Abstract
Se describe un procedimiento para reducir las impurezas de carbonilo en una reaccion de carbonilacion, para la produccion de ácido acético; la corriente de recirculacion de yoduro de metilo que es dirigida a un reactor de carbonilacion para carbonilar metanol o acetato de metilo a ácido acético, es tratada para remover las impurezas de carbonilo llevando a reaccion la corriente de yoduro de metilo formada en la reaccion con un compuesto amino acuoso que reaccione con los carbonilos para formar derivados nitrogenosos solubles en agua, separando una fase de yoduro de metilo orgánico de una fase de derivado acuoso, y destilando la fase de yoduro de metilo para remover impurezas más pesadas; se ha descubierto que el tratamiento de la corriente de recirculacion de yoduro de etilo hacia el reactor de carbonilacion reduce en gran parte los carbonilos presentes en el producto de ácido acético; la formacion de nitrilo a partir del derivado nitrogenoso durante la destilacion puede ser llevada al mínimo añadiendo agua al sistema.
