ABSTRACT:
Solid solutions of magnesium oxide-aluminum oxide related to hydrotalcite and what previously has been referred to as synthetic hydrotalcites, have been prepared with a surface area in excess of 250 m.sup.2 lg, especially at low Mg/Al atom ratios. Such high surface area materials are found to be quite effective in the aldol condensation of aldehydes, and in particular in the conversion of n-butyraldehyde to 2-ethyl-2-hexenal in high yield and with good selectivity in a liquid phase reaction at temperatures under about 200.degree. C.
