Wang, Song; Tian, Chengcheng published the artcile< Polyvinylpolypyrrolidone supported Bronsted acidic catalyst for esterification>, Electric Literature of 21876-43-7, the main research area is polyvinylpolypyrrolidone support Bronsted acidic catalyst esterification.
A polyvinylpolypyrrolidone (PVPP) supported Bronsted acidic catalyst ([PVPP-BS]HSO4) was prepared by coupling SO3H functionalized polyvinylpolypyrrolidone with H2SO4 in this work. After the characterization through FT-IR, FESEM, TG, BET, and elemental anal., it was found that 1,4-butane sultone (BS) and sulfuric acid reacted with PVPP and were immobilized on PVPP surface. The prepared [PVPP-BS]HSO4 catalyst shows high catalytic activity for a series of esterification reactions and could be separated from the reacted mixture easily. Moreover, this catalyst could be recycled and reused for six times without significant loss of catalytic performance.
