Effects of Na 2CO 3 impregnation on the catalytic activity of Mg 3(PO 4) 2 in the gas-phase conversion of 2-hexanol and the alkylation of aniline with methanol

Abstract

Various Na 2CO 3-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.
