摘要
The transesterification of cottonseed oil to biodiesel catalyzed by ionic liquids was studied. Several water-stable Bronsted-acidic ionic liquids with an alkane sulfonic acid group were synthesized. These ionic liquids show good catalytic activity for the transesterification of cottonseed oil. The catalytic activity of each ionic liquid is dependent on its cation. The ionic liquid 1-(4-sulfonic acid) butylpyridinium hydrogen sulfate shows the best catalytic activity, which is nearly the same as the catalytic activity of concentrated sulfuric acid. The produced biodiesel can be separated via simple decantation, and the ionic liquids can be reused after distillation.
