| titleOfInvention | Synthetic method of epoxy-terminated polyether |
| abstract | The invention discloses a method for synthesizing epoxy-terminated polyether, which adopts self-made solid acid Zn (ClO) 4 ) 2 Or Al (ClO) 4 ) 3 As a catalyst, polyether and epichlorohydrin are subjected to ring-opening reaction in a microchannel reactorAnd then carrying out a ring-closing reaction in the presence of solid alkali to obtain a crude product, and refining the crude product to obtain the epoxy-terminated polyether. The method has the characteristics of high selectivity, short reaction time, less side reaction, less consumption of epoxy chloropropane and the like. |
