| titleOfInvention | Application of microorganisms in the preparation of end-capped polyethers, and method for preparing end-capped polyethers using immobilized microorganisms |
| abstract | The invention discloses an application of microorganisms in the preparation of end-capped polyethers, and a method for preparing end-capped polyethers by using immobilized microorganisms. The deposit number of the Geotrichum candidum is CCTCC No. M2013114; the deposit number of the Corynebacterium portugaliens is CCTCC No. M205116; the deposit number of the Pichia melanoderma is CCTCC No. M205117. The preparation method includes: preparing a fermentation medium containing hydroxypolyether; immobilizing the mixed bacteria of Geotrichum candidum, Corynebacterium portuguese, and Pichia membranum on an immobilized template to form immobilized microorganisms; The microorganisms are added to the fermentation medium, and shaken at 25-45°C for 5-10 hours to obtain suspension 1; monohydroxypolyether and end-capping reagent are added to suspension 1, and shaken at 25-45°C The reaction is shaken for 5-10 hours, the reaction solution is added with a solvent for extraction, and the solvent is removed under reduced pressure to obtain an end-capped polyether product. The preparation method of the invention has high yield, is simple and economical, and is favorable for continuous production. |
