Abstract
The effect of alkali metal ions (Na+ or K+) on the acid–base and catalytic properties of Zn-Mg(Zr)Si oxide systems in the process of obtaining 1,3-butadiene from ethanol was studied. It was found that the modification of Zn-MgSi oxide systems promotes an increase in the 1,3-butadiene selectivity (at temperatures ≥670 K) by reducing the number of formation sites of by-products. In the composition of Zn-ZrSi oxide systems, alkali metal cation additives lead to a decrease in the ethene and diethyl ether selectivity due to a decrease in the content of strong acid sites that are active in the ethanol dehydration reaction.
