摘要
Polyaniline nanoparticles doped with 12-tungstophosphoric acid was prepared with different loading amounts of 12-tungstophosphoric acid. Doped polyaniline was characterized by XRD, SEM, and FT-IR techniques and the Keggin anion of heteropoly acid was detected on the polymer. Doped polymer was used as heterogeneous solid acid catalyst for the synthesis of 2-substituted benzimidazoles by the reaction of o-phenylenediamine with various types of aldehydes. The activity and reusability of the catalyst were found to be good.
