ABSTRACT:
An alkylene oxide, e.g. ethylene oxide, is prepared from the corresponding alkylene carbonate, e.g. ethylene carbonate, in the presence of an effective amount of a quaternary arsonium halide. The quaternary arsonium halides are also effective catalysts for the reverse reaction, that is, to form alkylene carbonates from the corresponding epoxide and carbon dioxide.
