MIXED OXIDE CATALYSTS WITH ORDERED MESOPORES, METHOD OF PREPARING THE SAME AND METHOD OF PRODUCING ESTER COMPOUNDS USING THE SAME

摘要

The present invention provides a complex oxide catalyst having cylindrical regular mesopores and excellent acid characteristics and a manufacturing method thereof. A complex oxide catalyst according to the concrete example of the present invention includes tungsten oxide, zirconium oxide, and silicon oxide. The atomic fraction of the tungsten and the silicon is 0.1/1-0.14/1, and the atomic fraction of the zirconium and the silicon is 0.1/1-0.14/1. Moreover, the present invention provides a method for effectively manufacturing a high-value ester compound from ethanol and a carboxylic acid compound using the complex oxide catalyst.
