Abstract
La presente invención se refiere a procedimiento para mejorar la actividad de catalizadores de plata con soporte para la preparación de óxido de etileno por reacción de etileno con oxígeno o aire, en el cual el catalizador, para la aplicación de 1 a 1000 mg de cesio por kilogramo de catalizador, es impregnado con una solución a base de por lo menos un compuesto de cesio y de un disolvente tomado del grupo de los alcoholes saturados alifáticos inferiores y agua, la impregnación se lleva a cabo a una temperatura de 60 a 200 grados C y la solución de impregnación en exceso es separado del catalizador impregnado, caracterizado porque se utiliza una solución de impregnación, que consta de hidróxido de cesio, de un alcoholato de cesio de un alcohol saturado alifático inferior, o de una mezcla de los mismos como compuesto de cesio, y de un alcohol saturado alifático inferior y de 0 a 20 por ciento en peso de agua en calidad de disolvente.
