The synthesis of chalcone system -C=C-C=O is relatively easy to prepare, usually highly reactive and are starting point of preparation of various bioactive compounds. This, -unsaturated ketones (chalcones) can be synthesized by Claisen-Schmidt condensation of different aromatic aldehydes with ketone and their cyclization with hydrazine hydrate in basic condition. Numerous pyrazoline derivatives have been found to possess considerable biological activities, which stimulated the research activity in this field. Amongst all the nitrogen containing five member heterocycles, it have proved to be...

Merging of all the four unsaturation, epoxy, ester and urethane segments into one polymer chain has not received attention academically and technically. Certain properties of thermoplastics may also be improved via blending or addition to an unsaturated resin is another possibility. In order to improve certain properties of such reported polymers their blending with commercial vinyl esters (epoxy resin) such as vinyl ester epoxy resin may afford a commercially important material for wide industrial applications. Hence the present report comprises synthesis of poly (urethane-ester) having...

Kinetic and thermodynamic study of removal of ionic dyes on low cost adsorbents and their derivatives. Four ionic dyes belonging to different classes were selected. The locally available low cost materials like raw agricultural wastes, carbonized agricultural wastes, surfactant modified agricultural wastes, surfactant modified agricultural waste carbon, low cost clays and low cost nanoadsorbents were evaluated for the adsorption of dyes from simulated dye effluent containing dyes. The effect of experimental conditions like effect of concentration, pH, temperature and reaction time were...
