<p>Process for Preparing Alkylene Oxides from Alkylene Carbonates Inventor Robert M. Weinstein 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.</p> |
