Magnetically recyclable basic polymeric ionic liquids for efficient transesterification of Firmiana platanifolia L.f. oil into biodiesel

Magnetically recyclable basic polymeric ionic liquids for efficient transesterification of Firmiana platanifolia L.f. oil into biodiesel
Biodiesel, typically derived from non-edible vegetable oils via heterogeneous catalysts, is being deemed as a promising alternative to fossil fuels. Herein, basic polymeric ionic liquids (PILs) immobilized on magnetic mesoporous carrier (Fe3O4@SiO2@SBA-15), FnmS-PILs, were synthesized through the facile radical polymerization and anion exchange methods, and were further utilized to catalyze transesterification of non-food feedstock-crude Firmiana platanifolia L.f. oil (CFPO, acid value of 1.20 mg KOH/g) into biodiesel directly. The characterization results demonstrated that FnmS-PILs with uniform core–shell structure, moderate surface area (153.2 m2/g), pore size (4.1 nm), strong magnetism (13.6 emu/g) and relative higher basicity (2.3 mmol/g) exhibited high catalytic performance, giving a high biodiesel yield of 92.8 wt% under mild reaction conditions (9/1 methanol/oil molar ratio, 4 wt% catalyst dosage at 85 °C for 5 h). Furthermore, kinetic study was also investigated accordingly, wherein the activation energy was found to be 51.6 kJ/mol along with a determined pseudo first order model. More importantly, the catalyst could be recovered easily by means of magnetic force and remained sufficiently active in five consecutive cycles.
