Abstract: |
Amino acid ionic liquids (AAILs), as a new type of functionalized ionic liquid with dual functions of solvent and catalyst, have great potential for application in the process of catalytic preparation of biodiesel. In AAILs, amino acids can be either anions or cations. The relationship between the types, properties and structure of AAILs, and the recent research progress on using AAILs as catalysts to prepare biodiesel were summarized, and the mechanism of AAILs in catalyzing esterification and transesterification to produce biodiesel were analyzed so as to provide a basis for the application of AAILs in the biodiesel preparation process. |
