A novel hybrid flocculant of acrylamide and cellulose was synthesized by using microwave irradiation method. Cellulose was extracted from kenaf by using TAPPI method. 57.4% of percentage grafting and efficiency has been obtained from the grafting process. The hybrid flocculant properties were characterized by using FTIR spectroscopy, FESEM and elemental analysis. Additional peaks that appear in FTIR result, presence of nitrogen in elemental analysis and granular structure of PAM attached in fibrillar structure of cellulose proved that PAM was successfully grafted onto cellulose backbone.

: A new series of pyrano[2,3-b]quinolines were synthesized from 3-formylquinolin-2(1H)-ones via Knoevenagel condensation followed by cyclization reaction of ethyl cyanoacetate using DMSO as solvent. This methodology is a simple; clean, fast, efficient, eco-friendly, less reaction time with an improvement in the yield and purity of the product. The structures of newly synthesized compounds were confirmed by IR, NMR, Mass and elemental analysis.
