摘要：

The objective of the investigation was to evaluate the catalytic efficiency of a solid base catalyst (SBC) derived from coal combustion fly ash to synthesize dibenzylideneacetone (DBA, 94% yield). The catalyst was produced using potassium hydroxide (30 wt.%) on thermally activated F-type fly ash. The physicochemical, mineralogical and morphological characterization of the fly ash and catalyst were performed using XRF, FT-IR, BET surface area analyser, XRD and SEM-EDS. The results of such analysis revealed that the catalyst obtained was associated with strong basic hydroxyl (-OH) sites that were highly suited to produce DBA by crossed aldol condensation reaction.
