Abstract

La presente invención se refiere a un método para preparar un compuesto orgánico polimerizable etilénicamente insaturado, caracterizado porque se somete un producto reaccionante o mezcla de productos reaccionantes a una destilación para su purificación y recuperación, el mejoramiento de la destilación consiste en destilar dicho producto reaccionante o mezcla de productos en presencia de un sistema inhibidor en fase líquida conteniendo un inhibidor fenólico y un compuesto soluble de manganeso o de cerio en combinación con un inhibidor en fase vapor seleccionado del grupo consistente en óxido nítrico y una sal amónica de N-fenil-N-nitrosohidroxilamina.
