Some series of aryl (E) 2-propen-1-ones have been synthesized by Fly-ash:H2O catalyzed aldol condensation of aryl methyl ketones and substituted benzaldehydes at reflux condition in atmospheric pressure. The yields of chalcones are higher than 60%. These chalcones were characterized by their physical constants and spectral data, for known compounds their purities were checked with the physical constants and spectral data earlier published in the literature. The effects of solvents on the product have been studied.

The green catalyst Fly-ash:PTS has been prepared and characterized by IR and SEM analysis. Using this catalyst some aryl chalcones have been synthesized by aldol condensation of aryl methyl ketone and substituted benzaldehydes. It has been observed that this reaction yields more than 85% of the product. These chalcones have been characterized by their physical constants and spectral data following the procedures published in literature. The effect of substituents on the spectral data of the chalcones, synthesized, has been studied using single and multi-regression analysis with Hammett equation. The antibacterial and antifungal activities of these chalcones have been studied using Bauer-Kirby method.
