摘要: This article reports on the catalytic activity of soluble poly(styrenesulphonic) acid (PSSA) in three different reactions driven by acidic sites: tributyrin methanolysis, biodiesel synthesis and xylose dehydration to furfural. The PSSA catalyst, polar media used these reactions, displayed larger than other non-soluble sulphonic solid catalysts studied (Amberlyst 36, Amberlyst 70 Nafion®-SAC13). ultrafiltration catalyst allowed retention reutilisation for several runs. No significant decay was observed reaction repeats investigated. All results demonstrated that PSSA, a material can be obtained from polystyrene waste, is an excellent reusable conducting demanding sites.
