Recently, we were trying to synthesize stannous-surfactant based catalyst for our polymerization process. The method it self was simple, by mixing SnCl2 dihydrate solution with surfactant solution until we obtained the precipitate according to literature. Previously we attempted to synthesize it with distilled water as solvent but the result obtained was unsatisfactory. Then we re-attempted the synthesize using ethanol 96% as solvent, but the EDX result showed strong deviation from our theoritical calculations. What could went wrong ? Should we change the metal, surfactant, or solvent ?
