摘　　要：采用超细氧化镁作催化剂 ,乙酰乙酸乙酯和乙酸酐为原料 ,对乙酰丙酮的合成进行了研究 ,确定了最佳工艺条件 :反应时间 18h ,温度 130℃ ,原料摩尔比n(乙酰乙酸乙酯 ) /n(乙酸酐 ) =1.0 ,催化剂用量 (MgO) =0 .75 % ,乙酰丙酮的收率 95Synthesis of acetylacetone by acetoacetic ester and acetic anhydride on superfine MgO was studied. studying the influence factors, the optimum process conditions were determined, including a reacting time 18 h, temperature 130 ℃, amount of catalyst MgO 0.75 %, and mole ratio n(acetoacetic ester)/n(acetic anhydride) 1.0. On these conditions, the yield of acetylacetone was 95 %.
