| titleOfInvention | Method for recovering tert-butylamine and isooctanoate from potassium clavulanate still residue |
| abstract | The invention belongs to the technical field of pharmacy, and relates to a method for recovering tert-butylamine and isooctanoate from potassium clavulanate raffinate. Set layering to obtain the water phase and isooctanoic acid oil phase containing tert-butyl ammonium sulfate; use alkali to adjust pH to basicity to the water phase containing tert-butyl ammonium sulfate salt, then distill to obtain tert-butylamine; isooctanoic acid oil phase is by adding lye , converted into isooctanoate aqueous solution, purified by ultrafiltration, decolorization and impurity removal with macroporous adsorption resin, and then evaporated, concentrated and crystallized to obtain high-quality isooctanoate. The invention realizes the recovery and reuse of the residual liquid from the kettle, creates a new economic growth point for the enterprise, reduces and avoids the environmental pollution caused by the organic matter, and achieves the strategic goal of safety, environmental protection and win-win for the enterprise. |
