Abstract
Procedimiento para la obtención de un catalizador, mediante la aplicación de un éster cromato sobre un substrato, que contiene dióxido de silicio y mezcla del producto de reacción (componente A) con un compuesto orgánico de aluminio (componente B), caracterizado porque el producto de reacción se obtiene aplicando un éster cromato de la fórmula (RO)2CRO2. En la que R significa un grupo alcohilo o aralcohilo terciario, con 4 hasta 24 átomos de carbono, sobre un óxido u óxido mixto de silicio y/o de aluminio y, en ausencia de un hidrocarburo no saturado , se trata con un compuesto de titanio de la fórmula Ti (OR4)4 en la que R4 significa un radical alcohilo de cadena recta o ramificada con 1 hasta 12 átomos de carbono, en la proporción de Cr:Ti de 1:1 hasta 1:10.
