Abstract

Un proceso para la recuperacion de acrilonitrilo o metacrilonitrilo obtenido del efluente de reactor de una reaccion de amoxidacion de propileno o isobutileno que comprende el paso del efluente de reactor a través de una columna absorbedora, un primer decantador, una columna de recuperacion, un segundo decantador y una columna separadora en donde la mejora comprende el mantenimiento de la temperatura interior del primero y segundo decantador entre aproximadamente 32 degree F hasta 75 degree F.
