Zusammenfassung:	The invention relates to a preparation method and application of a magnetic solid base catalyst for synthesizing biodiesel, belonging to the technical fields of environment catalysis and energy sources. The preparation method comprises the following steps of: mixing a raw material of a magnetic substance, a raw material of an active component and TiO2, then roasting at 300-500 DEG C for 3-6h, cooling to the room temperature, and then grinding and screening with a 120-mesh sieve, roasting at 900-1200 DEG C for 5-12h, and naturally cooling to the room temperature to obtain the magnetic solid base catalyst, wherein the magnetic substance is one of Fe3O4, Fe2O3, NiO, CoO and Mn2O3, and the raw material of the magnetic substance is from corresponding hydroxides, carbonates or nitrates of Fe3O4, Fe2O3, NiO, CoO and Mn2O3; the active component is one of Li, Na, K, Rb and Cs oxides, and the raw material of the active component is from corresponding hydroxides, fluoride salts, carbonates, nitrates or acetates of the L
