Abstract

Procedimiento para la preparación de ácido acético y/o de acetato de metilo por la reacción sobre metanol de una composición que comprende hidrógeno y monóxido de carbono, representando el monóxido de carbono al menos un 75% en moles, a una temperatura del orden de 180ºC como máximo y en presencia de una cantidad eficaz de cobalto, caracterizado porque la reacción se conduce en presencia de un yoduro iónico por lo menos y cuando menos un halogenuro covalente, eligiéndose el catión del yoduro iónico entre el grupo que está constituido por los cationes de metales alcalinos, cationes de metales alcalinotérreos, cationes amonio, cationes amonio cuaternario, cationes fosfonio y cationes fosfonio cuaternario, siendo la relación I-/Co (en átomos-gramo) mayor o igual a 10 y estando comprendida entre el 1 y 30 % la relación X/I- (en átomos -grano) en la cual x representa un átomo de halógeno procedente del halogenuro covalente.
