摘要

The aldol condensation using cyclopentanone with valeraldehyde Was conducted at hydrotalcites catalysis. The catalyst Was obtained by I calcining the hydrotalcite precursor (Mg/Al = 3:1) at 773 K Its reaction performance was evaluated on the various Molar ratios of I cyclopentanone to n-valeraldehyde. A good, Catalytic selectivity Of 90 % and a high conversion of 93 % were achieved udder mild conditions.
