摘要：
Various Na2CO3-impregnated magnesium orthophosphates have been synthesized and characterized by XRD, TGA, DRIFT and adsorption measurements. No decomposition or reaction of the carbonate at temperatures up to 773 K was observed. The textural and chemical properties of the catalysts were found to be modified by the carbonate loading. These catalysts are active in the gas-phase transformation of 2-hexanol and in the N-alkylation of aniline with methanol. The activity and selectivity of the catalysts in both reactions are related to their acid-base properties and carbonate content. (C) 1998 Elsevier Science B.V. All rights reserved.
