| description | To solve the problem that a conventionally known method for purifying halogen-containing polyether can efficiently purify a small amount of polyether, on the other hand, when treating a large amount of polyol, precipitated aluminum fine particles may cause clogging, which may cause lowering of a filtration rate.SOLUTION: A method for producing chlorine-containing polyether polyol includes following (A) a polymerization step and (B) a purification step. The (A) polymerization step is a step of performing a polymerization reaction of epichlorohydrin using a catalyst composition containing an onium salt, an aluminum compound and an active hydrogen-containing compound, and producing a crude solution of chlorine-containing polyether polyol. The (B) purification step is a step of adding water to the crude solution of the chlorine-containing polyether polyol obtained by the (A) polymerization step, heating and stirring the mixture for 15 minutes or longer, then removing water therefrom, and filtering the mixture using a filtration auxiliary.SELECTED DRAWING: None
【課題】従来知られているハロゲン含有ポリエーテルの精製処理方法では、少量を処理するには効率よく精製できる一方で、多量のポリオールを処理しようとすると、析出したアルミニウム微粒子が目詰まりを引き起こし、濾過速度の低下を引き起こすことがあった。【解決手段】以下の（Ａ）重合工程及び（Ｂ）精製工程を含む塩素含有ポリエーテルポリオールの製造方法。（Ａ）重合工程；オニウム塩、アルミニウム化合物及び活性水素含有化合物を含む触媒組成物を用いて、エピクロロヒドリンの重合反応を行い、塩素含有ポリエーテルポリオールの粗液を製造する工程。（Ｂ）精製工程；（Ａ）重合工程により得られた塩素含有ポリエーテルポリオールの粗液に、水を添加し１５分以上加熱攪拌を行った後、水を除去し、濾過助剤を用いて濾過を行う工程。【選択図】 なし |
