Abstract
Un proceso para la preparación de estireno o estirenos sustituidos de la fórmula general Ar-CR=CH2 donde Ar es un grupo fenilo, tolilo o xililo y R es H o un grupo metilo que comprende deshidratar en fase gaseosa 1- feniletanol o 1-feniletanol sustituido de la fórmula general Ar-C(R)(CH3)-OH, donde Ar y R son como se ha definido anteriormente, en presencia de un catalizador sólido ácido que contiene una zeolita y un material aglutinante, en el que la proporción en peso de zeolita respecto al aglutinante está en intervalo de 1:99 a 90:10 y al que le corresponde la siguiente relación: 0 < K < 5 (1) con: K = V/S * [(Pz * fz) + (Pb * fb)]1/2 (2) donde: V/S es la relación volumen/superficie del catalizador utilizado en mm; fz es la fracción en peso de zeolita presente en el catalizador en gramos de zeolita por gramo de catalizador; fb es la fracción en peso de aglutinante presente en el catalizadoren gramos de aglutinante por gramo de catalizador; Pz es la productividad intrínseca de la zeolita expresada como gramos de estireno producidos por gramo de zeolita por hora, medida para muestras de zeolita pura de un tamaño de partículas < 0,1 mm a la temperatura aplicada en la deshidratación en fase gaseosa y con una conversión del 1- feniletanol en estireno por debajo de 80%; y Pb es la productividad intrínseca del aglutinante expresada como gramos de estireno producidos por gramo de aglutinante por hora, medida para muestras de aglutinante puro de un tamaño de partículas < 0,1 mm en las mismas condiciones utilizadas para determinar Pz.
