Biodiesel, as a kind of renewable and clean energy, is becoming a hotspot in new energy field. To reduce the production cost and promote the application, the development directions of biodiesel were cheap raw materials, noval synthesis process and efficient catalyst. Ionic liquid as a noval green solvent and catalyst with designable function exhibited unique application future in the chemical reaction and process development. The application of ionic liquid in the field of biodiesel production was a new direction developed in recent years. |
