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
