| description | The present invention relates to a method for preparing a purified styrene composition, wherein the method comprises providing a crude composition containing 70% by weight or more styrene based on the total weight of the crude composition and subjecting the crude composition to at least one crystallization step, wherein the at least one crystallization step comprises at least one of a static crystallization stage and a dynamic crystallization stage, and wherein the crude composition contains one or more impurities selected from the group consisting color inducing species, oxygenates, sulfur species, alpha-methylstyrene and arbitrary combinations of two or more thereof.
La presente invención se refiere a un método para la preparación de una composición de estireno purificado, en donde el método comprende proporcionar una composición en bruto que contiene el 70 % en peso o más de estireno, basándose en el peso total de la composición en bruto, y someter la composición en bruto a al menos una etapa de cristalización, en donde la al menos una etapa de cristalización comprende al menos una de una fase de cristalización estática y una fase de cristalización dinámica y en donde la composición en bruto contiene una o más impurezas seleccionadas del grupo que consiste en especies inductoras de color, oxigenados, especies de azufre, alfa-metilestireno y combinaciones arbitrarias de dos o más de los mismos. |
