Synthesis and Characterization of some New 3,3'-(1,4-Phenylene) Bis (1-(4-Aminophenyl) Prop-2-en-1-one) Amide Derivatives

Abstract

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.

Effect of grafted polyurethane on oil spill remediation in the aquatic environment

“…Three hydrophobic/oleophilic compounds were pre-prepared and fully characterized, as reported in our previous work [16] are exhibited in Table 1.…”

“…Recently, hydrophobic materials have been widely used to modify the surface of hydrophilic sponges, and the modified sponges have significantly improved adsorption performance. To improve the oleophilic/hydrophobic properties of commercial flexible PU sponge, grafted copolymerization with three new oleophilic compounds ending in a vinyl group [16] was used, with divinyl benzene (DVB) as the crosslinker, benzoyl peroxide (BPO) as the initiator, and toluene as the solvent. The crude oil and commercial oil (diesel fuel) samples were chosen for the te s ts, and the sorption capacities of the ungrafted FPU cubes and modified FPU cubes in pure water, pure oil (the crude oil and diesel fuel), and water-oil sy s tems were scrutinized and compared in detail.…”

Synthesis of Functionalized Flexible and Rigid Polyurethane for Oil Spill Treatment

“…The new pre-prepared hydrophobic/oleophilic acrylamide phenyl chalcone palamitamid monomer [26] was used to be crosslinked by divinylbenzene and in situ grafting polymerization on the FPU and RPU foam cubes. Its structure is exhibited in Fig.…”

“…The flask was then filled with a mixture containing 0.3 g of each acrylamide phenyl chalcone palamitamid and 0.003 g of the cross-linker divinylbenzene (DVB). After 6 hours of interaction under stirring (500 rpm) and a nitrogen gas atmosphere at 80 °C, the cubes were washed with ethanol and deionized water several times, then dried at 60 °C under vacuum for 48 hours [25,26]. Schemes 1 and 2 show the grafting reactions of acrylamido phenyl chalcone palamitamid-crosslinked-divinylbenzene onto FPU and RPU, respectively.…”
