A new amide derivative series [A1-A8] was prepared in good yield by direct reflux condensation of bis-chalcone [3,3'-(1,4-phenylene) bis (1-(4-aminophenyl) prop-2-en-1-one)] with different carboxylic acids and acrylamide in the presence of a suitable solvent and amount of sodium hydroxide (NaOH). The structures of the synthesized amide were characterized by various spectral techniques, including FTIR (Fourier-Transform Infrared Spectroscopy), 1H-NMR (Proton Nuclear. Magnetic Resonance Spectroscopy), and mass spectroscopy, and the resultant spectra confirmed the expected structure of the prepared bis-chalcone derivative.

The aquatic environment may be seriously harmed when cargo gases, diesel, and their compounds leak or are accidentally spilled onto the water's surface. Oil exploration also leads to water contamination. The remaining oil coats the water's surface, resulting in the formation of a thin emulsion of water and oil. Three novel compounds with long chains of linear alkyl groups were grafted to flexible polyurethane (R-FPU) to clean up oil spills. The sorption testing was thoroughly examined and contrasted with the aid of crude oil, diesel fuel, and water-oil systems. It was found that as compared to ungrafted FPU, the chemical sorption of crude oil and diesel fuel was boosted by modified FPU cubes, while water sorption was reduced by roughly 57%. The sorption competence of the modified FPU was highly correlated with the length of the alkyl chain, with the longer alkyl chain significantly increasing sorption capacity. The results demonstrate that oil may be successfully cleaned using modified FPU cubes.
