Abstract

PROCEDIMIENTO PARA LA OBTENCION DE OXIDO ETILENICO. CONSISTE EN LA OXIDACION DE ETILENO CON OXIGENO, EN PRESENCIA DE UN CATALIZADOR DE PLATA, A UNA TEMPERATURA ENTRE 200 Y 300 GC, AGREGANDO COM MINIMO A LA MEZCLA DE GAS, QUE SE COMPONE DE ETILENO, OXIGENO MOLECULAR Y GASES INERTES, UN METAL ALCALINO EN FORMA ELEMENTAL O LIGADA, EN UNA CANTIDAD COMPRENDIDA ENTRE 1 PPB-GRAMO-ATOMO Y 1 PPM-GRAMO-ATOMO, CALCULADO COMO METAL ALCALINO; LA AGREGACION SE PUEDE HACER EN FORMA CONTINUA O A INTERVALOS. LOS METALES ALCALINOS, POTASIO O CESIO, SE AGREGAN EN FORMA DE SALES, SIENDO NORMAL UNA MEZCLA DE FORMIATO DE POTASIO Y ACETATO DE CESIO. LA AGREGACION SE REALIZA PASANDO EL GAS ALIMENTADO A TRAVES DE LAS SALES EN FORMA SOLIDA, A TEMPERATURA ELEVADA, O AÑADIENDO VAPOR DE LA SAL EN LA MEZCLA DE GAS.
