摘要: 以糠醛和丙酮为原料,通过羟醛缩合反应制备二亚糠基丙酮;采用FT-IR,1H-NMR,XRD方法对产物进行表征。结果表明:缩合产物经表征证实为二亚糠基丙酮;以0.1 mol/L KOH溶液为催化体系,在反应温度为20 ℃、反应时间为10 h、n(糠醛):n(丙酮)为2.0的条件下,产品二亚糠基丙酮收率达98.5%,纯度为98%。
关键词: 糠醛, 二亚糠基丙酮, 羟醛缩合, 催化转化
Abstract: 1,5-bis(2-furanyl)-1,4-pentadien-3-one was synthesized by the aldol condensation reaction of furfural and acetone in inorganic base medium and is identified by FT-IR,1H-NMR and XRD. The optimum conditions for the reaction are: reaction medium of 0.1 mol?L-1 KOH (aq), reaction temperature 20℃, reaction time 10h, the molar ratio of furfural to acetone 2:1. Under the optimum conditions, the yield of product is 98.5 % with a purity of 98%.
Key words: furfural, 1,5-bis(2-furanyl)-1,4-pentadien-3-one, aldol condensation, catalytic conversion
