摘　　要：以乙酰乙酸乙酯和乙酸酐为原料,分别用MgO和Mg(OH)2作为催化剂催化合成乙酰丙酮,研究了MgO和Mg(OH)2在500～900℃下焙烧后对合成乙酰丙酮反应活性的影响。结果表明,固体强碱MgO和Mg(OH)2具有相似的催化活性。Acetylacetone has been synthesized by the reaction of ethyl acetoacetate and acetic anhydride catalyzed by MgO and Mg(OH)2 respectively. Influence of MgO and Mg(OH)2 on the reaction activity of acetylacetone after roasted at 500～900 ℃ was studied. The results showed that the solid strong base of MgO and Mg(OH)2 had similar catalytic activity.
