Abstract

Un proceso para purificar una corriente de etanol que comprende subproductos, como por ejemplo aldehído, acetales, y/o ésteres, en el cual se extrae una corriente lateral que comprende etanol de una columna de destilación. La corriente lateral puede tener una concentración reducida de aldehídos, lo que reduce la formación de acetales en una subsiguiente purificación de la corriente de etanol.
