The aim of this work has been to compare the activity and selectivity of Mg-Fe
mixed oxides in the aldol condensation of furfural with that of previously studied
Mg-Al mixed oxides. Mg-Fe mixed oxides were prepared by thermal pre-treatment
of hydrotalcites with a Mg/Fe molar ratio from 1.1 to 7.6. Structural and textural
properties of Mg-Fe mixed oxides were analysed by using of XRD and N2-
adsorption. It was found that Mg-Fe mixed oxides exhibited lower conversion of
furfural in contrast to the Mg-Al mixed oxides, but being more selective to 4-(2-
furyl)-3-buten-2-one (FAc). The difference in the conversion of furfural was
relatively low among the Mg-Fe mixed oxides with the Mg/Fe molar ratio in the
range of 1.1-5.5.
