Latest Patents

Bufan Ren's latest patents include the "Glyphosate dimethylamine salt crystal, preparation method and use thereof." This invention provides a herbicidal active ingredient, a dimethylamine salt crystal of N-phosphonomethyl glycine (glyphosate). The preparation process involves adding glyphosate and a suitable amount of solvent into a conventional reactor, followed by the introduction of dimethylamine gas for reaction. The reaction temperature is controlled between 5 and 90°C. After the reaction is complete, the temperature is gradually reduced, resulting in the precipitation of a crystalline dimethylamine salt of glyphosate.

Another significant patent is the "Preparation of solid ammonium glyphosate using organic solvent in extraction." This method prepares ammonium glyphosate suitable for water-soluble solid formulations. The process involves adding glyphosate and water into a reactor, introducing ammonia for reaction, and forming an aqueous solution of ammonium glyphosate. A water-soluble organic solvent is then added to decrease the solubility of ammonium glyphosate, leading to its crystallization. The organic solvent can be recovered and reused, enhancing the efficiency of the process.
