Abstract

Un proceso para estabilizar una mezcla de productos de metátesis de olefinas, de preferencia, contra la isomerización de la doble ligadura y degradaciones térmica y química. El proceso involucra (a) poner en contacto una mezcla de productos de metátesis de olefinas que comprende una o más olefinas producidas en un proceso de metátesis, un catalizador de metátesis que comprende un metal catalítico y una o más ligandos, opcionalmente, uno o más productos de degradación del catalizador de metátesis y, opcionalmente, uno o más metales derivados de fuentes diferentes al catalizador o producto(s) de degradación del catalizador con un absorbente, más preferiblemente carbón; o alternativamente, b) sujetar la mezcla de productos de metátesis de olefinas a una destilación de dos pasos, de preferencia, que incluye evaporación de película lavada de trayectoria corta. Se describe una mezcla estabilizada de productos de metátesis de olefinas que contiene una o más olefinas obtenidas en un proceso de metátesis y que tiene una concentración total de metal(es) de menos de aproximadamente 30 partes por millón en peso.
