In nature, polysaccharides are usually not in particulate form that can be used to form and stabilize emulsions. Instead, polysaccharide-rich sources must be physically, chemically, or enzymatically modified to obtain solid or semi-solid particles. In the current research, sodium alginate polysaccharide modified with dodecylamine to stabilize Pickering emulsion and use as a catalyst was prepared and with the help of Fourier Transform Infrared (FTIR), Scanning Electron Microscope (SEM), X-ray Energy Diffraction Spectroscopy (EDX), Light microscopy, zeta potential, contact angle were detected. In examining the performance of this compound in the formation of Pickering emulsion, the relevant and effective optimal conditions in the formation of the emulsion were eva‎luated and it was observed that the optimal conditions for the formation of a stable Pickering emulsion were pH=8, the amount of salt=10 mg, the amount of Pickering emulsifying agent 0.02 grams, The ratio of aqueous: organic phase is (1:2). It was observed that this catalyst has a good ability to perform Knoevenagel condensation in the formation of benzidine malononitrile and its derivatives with good efficiency.
