文摘

Diethyl carbonate (DEC) has been produced by the oxidative carbonylation of ethanol in thegas phase over a heterogeneous CuCl₂/PdCl₂ catalyst supported on activated carbon. Yields ofDEC with this catalyst are approximately 10 wt % with the byproducts diethoxymethane, ethylformate, and acetaldehyde also formed in significantly lower yields. Treatment of the catalystimmediately after preparation with potassium hydroxide enhances the production of DEC almost2-fold without increasing the amount of byproducts formed. The reactions that form DEC andthe byproducts occur in a parallel, rather than a sequential, manner indicating that it should bepossible to identify a catalyst which is more selective for DEC.
