Abstract

Se describe un metodo para operar un sistema que contiene epoxido que contiene un catalizador. El metodo comprende alimentar dioxido de carbono al sistema que contiene epoxido en una cantidad de desde 0.01 a 5.0 por ciento en peso; y mantener el sistema que contiene epoxido a una temperatura de desde 100degree C a 150degree C. El catalizador tiene una vida media de al menos 40 dias a 120degree C. La presente invencion permite que las resinas de intercambio de aniones en la forma de bicarbonato se utiliza para la hidrolisis de oxido de etileno a temperaturas que excedan 100degree C. La proporcion de hinchamiento del catalizador se minimiza y la vida util del catalizador se aumenta.
