REZENDE, Simone M. de et al. Evaluation of sulfonic resins as catalysts in transesterification of vegetable oils. Polímeros [online]. 2005, vol.15, n.3, pp.186-192. ISSN 0104-1428.

Different polymer supports based on styrene (S) and divinylbenzene (DVB) were synthesized and their morphology was characterized by optical and scanning electron microscopy. Sulfonic catalysts were prepared from these supports, characterized and their activities were evaluated in vegetal oil transesterification with methanol and compared with the performance of a commercial sulfonic resin. The synthesized catalysts showed results close to the commercial resin.

Keywords : Sulfonic resins; synthesis; characterization; heterogeneous catalysis; transesterification.
