- Synthetic method of stannous ricinoleate
-
The invention discloses a synthetic method of stannous ricinoleate. According to the method, two steps of reactions are adopted, ricinoleic acid is used as a raw material in the first step of reaction, and a solvent A is used for reacting with sodium hydroxide, sodium methoxide or a sodium methoxide methanol solution under certain reaction conditions to synthesize sodium ricinoleate; and in the second step of reaction, the sodium ricinoleate is used as a raw material to react with anhydrous stannous chloride, stannous chloride hydrate or stannous sulfate by using a solvent B under a heating condition to synthesize stannous ricinoleate. The solvent A is an alcohol solvent; the solvent B is an alcohol solvent, an aromatic solvent or a polar aprotic solvent; and the solvent A and the solventB can be recovered by a distillation method and can be recycled. The method has the advantages of low raw material cost, simple operation, less discharge of three wastes, high reaction efficiency andthe like.
