Catalysis Preparation of Biodiesel from Waste Schisandra chinensis Seed Oil with the Ionic Liquid Immobilized in a Magnetic Catalyst: Fe₃O₄@SiO₂@[C4mim]HSO₄.

ABSTRACT: The purpose of this study was to synthesize a magnetic material that could be easily separated by a magnetic field and combined the catalytic function of an acid/base ionic liquid with silicon for biodiesel preparation. A kind of magnetic catalyst-immobilized ionic liquid was synthesized by a three-step method. The synthesis conditions in each step were optimized by single-factor analysis. Under the optimum conditions, 206.83 mg of ionic liquid (>43.63%) was immobilized on SiO₂ (per gram). Heating under reflux was applied to extract Schisandra chinensis seed oil with an average yield of 10.9%. According to the biodiesel yields, Fe₃O₄@SiO₂@[C4mim]HSO₄ was the most efficient catalyst in the methyl esterification reaction. Under th
