Abstract

El objeto de la invención es un procedimiento para la elaboración de acroleína por deshidratación de la glicerina, en fase líquida o en fase gaseosa en cada caso con catalizadores de sustancias sólidas ácidas. Frente a los procedimientos ya conocidos, se puede elevar de acuerdo al invento la selectividad, rendimiento espacio-tiempo y el tiempo de permanencia de los catalizadores, donde se trata una mezcla glicerina-agua con un contenido de glicerina de 10 hasta 40 por peso a 180 hasta 340°C (fase líquida) o bien 250 hasta 340°C (fase gaseosa) en un catalizador de sustancias sólidas con un valor H0 (función ácida de Hammett) menor de +2, de preferencia menor de -3.
