The aldol condensation using cyclopentanone with valeraldehyde was conducted at hydrotalcites catalysis. The catalyst was obtained by calcining the hydrotalcite precursor (Mg/Al = 3:1) at 773 K. Its reaction performance was evaluated on the various molar ratios of cyclopentanone to n-valeraldehyde. A good catalytic selectivity of 90 % and a high conversion of 93 % were achieved under mild conditions.
在氢铝酸盐催化下,环戊酮与戊醛进行了醛缩合反应。催化剂是通过在 773 K 下煅烧氢铝酸盐前驱体(镁/铝=3:1)获得的。在温和的条件下,催化选择性达到 90%,转化率高达 93%。
