Abstract

Un procedimiento para la preparación de nitrilos insaturados a partir de olefinas, en presencia de un catalizador a base de antimonio, estaño, tungsteno, cobre y telurio, cuyo procedimiento consiste en: a) se prepara dicho catalizador haciendo la precipitación separada o simultáneamente a partir de sales o de compuestos solubles de antimonio, estaño, tungsteno, cobre y telurio y/o efectuando la descomposición térmica simultanea o separadamente de los compuestos convertibles en óxidos de los elementos anteriormente citados, por calentamiento, para obtener una combinación intima de los óxidos de dichos elementos; b) someter a tratamiento térmico, a una temperatura comprendida entre 500 y 1000º C y en atmósfera oxigenada, el catalizador procedente de la etapa a), para obtener un compuesto de formula: sba snb wc cud tee of en la cual, a se encuentra comprendido entre 1 y 10, b entre 1 y 10, c entre 0,01 y 5. d entre 0,01 y 5, e entre 0,01 y 5 y f es el numero de átomos de oxigeno de la combinación oxigenada que se obtiene combinando los elementos metálicos de la formula (1). C) someter a reacción de amoxidacion, con oxigeno y amoniaco como reactivos, en presencia del catalizador procedente de la etapa b), una olefina para obtener el correspondiente nitrilo insaturado.
