Biodiesel, as a kind of renewable and clean energy, is becoming one of the research and development hotspots in new energy fields. To reduce the production cost and prompt the technology application, several directions are developed for biodiesel research such as using cheap raw material, new synthesis process and efficient catalyst. Ionic liquid which is characterized by functional design is a green catalyst and solvent, and it has shown unique application prospect in the chemistry and process development. The application of ionic liquid in the field of biodiesel production is a new direction developed in recent years.In this paper, the research progress of ionic liquid in the biodiesel production by transesterification was reviewed. Effects of ionic liquid as solvent and catalyst on the biodiesel preparation process were analyzed and discussed respectively. On this basis, the major issues that need to be resolved were also pointed out.
