| description | To provide a method for producing polyether polyol which easily achieves high productivity, and a method for producing a polyurethane resin using the polyether polyol obtained by the production method.SOLUTION: A method for producing polyether polyol uses a batch type reactor 20A having a reaction tank 10 for reacting a catalyst with a mixed liquid containing cyclic ether, a cooling system for cooling the mixed liquid in the reaction tank 10 and stirring blades 2 and 2 for stirring the mixed liquid in the reaction tank 10, and has a member 2c which is a passage where the stirring blades 2 emit the mixed liquid toward the inner wall surface of the reaction tank 10 while moving the mixed liquid in the vicinity of a liquid surface in the reaction tank 10 by rotation in stirring upward.SELECTED DRAWING: Figure 1
【課題】本発明は、高生産性を実現しやすいポリエーテルポリオールの製造方法；および前記製造方法で得られたポリエーテルポリオールを用いるポリウレタン樹脂の製造方法を提供する。【解決手段】本発明のポリエーテルポリオールの製造方法は、触媒および環状エーテルを含む混合液が反応する反応槽１０と、反応槽１０内の混合液を冷却する冷却系と、反応槽１０内の混合液を攪拌する攪拌翼２，２とを有するバッチ式反応器２０Ａを用い、攪拌翼２が、撹拌時の回転によって反応槽１０内の液面付近の混合液を上方に移動させながら、反応槽１０の内壁面に向けて放射する流路となる部材２ｃを有する。【選択図】図１ |
