"ALDOL CONDENSATION USING SOLID BASIC CATALYST OF MgO AND Al2O3 HAVING A HIGH SURFACE AREA" 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 m2/g, especially at low Mg/Al atom ratios. Such high surface area basic materials are found to be quite effective as catalysts 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°C.
