Abstract

Procedimiento para aumentar la selectividad en la oxidación continua de etileno con oxígeno o con gases que contienen oxígeno para formar óxido de etileno en catalizadores de plata, que se caracteriza por el hecho de que mediante la variación periódica de la concentración inicial de etileno o de oxígeno o de ambos la reacción se efectúa en condiciones no estacionarias.
