| titleOfInvention | Method of purifying polyether compound |
| abstract | To provide a purification process which makes it possible to reduce the amount of an inorganic adsorbent to be used, shorten the time for separating a polyether and the inorganic adsorbent by filtration, and further reduce the amount of a metal derived from a double metal cyanide complex catalyst in a purified polyether thereby obtained. n A polyether is synthesized by ring opening polymerization of an alkylene oxide with an initiator having at least one hydroxyl group, in the presence of a double metal cyanide complex catalyst, then a powder of an inorganic adsorbent containing at least 50 vol% of fine particles having a particle size of at most 26 µm and further containing at least 90 vol% of fine particles having a particle size of at most 44 µm, is added to the above polyether, and a metal derived from the above double metal cyanide complex catalyst is adsorbed on the above powder, followed by separating the above powder from the above polyether. |
