Abstract
Procedimiento para la recuperación del isopreno de mezclas que lo contienen, particularmente para la recuperación de isopreno de alto grado de pureza a partir de una mezcla de hidrocarburos C5, caracterizado por el hecho de comprender las siguientes etapas: a) rectificación en una columna de rectificación mediante eliminación por la cabeza de los hidrocarburos C4, de los compuestos acetilénicos de bajo punto de ebullición y del 70% al 90% del isopentano, y mediante eliminación por el fondo de todos los productos de dimerización y/o polimerización formados durante el almacenamiento y del 30 al 60% de los hidrocarburos de alto punto de ebullición eventualmente presentes, siendo descargada en fase vapor la corriente que contiene isopreno por un plato de la zona de agotamiento de la columna.
