| titleOfInvention | A kind of synthetic catalyst of polyoxyethylene polymer and its synthetic method |
| abstract | The invention provides a synthetic catalyst for polyoxyethylene polymers, comprising component 1, component 2 and component 3, wherein component 1 is a crown ether, component 2 is a quaternary phosphine salt, and component 3 is an alkali Metal and/or alkali metal compounds. The synthesis catalyst of polyoxyethylene polymer can reduce the concentration of alkali metal ions in the product, improve product quality, and is suitable for high-standard industrial fields. The present invention also provides a method for synthesizing polyoxyethylene-based polymers. The compound containing active hydrogen is mixed with the above-mentioned catalyst, and then ethylene oxide is added in an oxygen-free or vacuum environment; the temperature is controlled at 100-180°C, The pressure is less than or equal to 1.0 MPa, and it is maintained for 1-8 hours to obtain a reaction product containing polyethylene oxide polymer; finally, an acidic compound is added to the reaction product for neutralization. The synthesis method provided by the invention is simple in operation, friendly to the environment, improves the quality of the synthesized product, and is suitable for high-standard industrial production. |
