Three novel alkaline guanidine ionic liquids as amphiphilic catalysts have been successfully synthesized for two-phase transesterification, which can efficiently improve the catalytic activity for the synthesis of biodiesel. They were characterized by a series of techniques including 1H NMR, thermal stability, electronegativity (DFT calculation), basicity and conductivity. It was demonstrated that...
A novel magnetic solid base catalyst CaO/CoFe 2 O 4 was successfully prepared with CoFe 2 O 4 synthesized by hydrothermal method as the magnetic core and applied to the transesterification of soybean oil for the production of biodiesel. The magnetic solid base catalysts were characterized by a series of techniques including CO 2 -TPD, powder XRD, TGA, TEM and...
