Preparation method of organic selenium compound |
| abstract |
A preparation method of an organic selenium compound, comprising the following steps: (1) hydrolyzing lignin to obtain a polyphenol having multiple structures; (2) reacting the polyphenol having multiple structures with at least one metal inorganic base to obtain a polyvalent phenolic hydroxyl carboxylate; (3) reacting the polyvalent phenolic hydroxyl carboxylate with SeO 2 to obtain a polyvalent phenolic hydroxyl selenium carboxylate double salt, the polyvalent phenolic hydroxyl selenium carboxylate double salt being an organic selenium compound. |
