Description
a)イソブテンを、液状有機相中でルイス酸触媒の存在で、重合させ、
b)有機相を、反応停止のために、1つの外周壁(Umfangswand)及び2つの端壁(Stirnwaenden)から形成される回転対称な混合室と、その中の回転駆動の混合ローターとを有するダイナミックミキサー中で、水性停止剤と混合し、その際に有機相を、外周壁中に設けられた第一の入口オリフィスを介して、かつ水性停止剤を、外周壁中に設けられた第二の入口オリフィスを介して導入し、かつ
c)外周壁中に設けられた出口オリフィスを介して、有機相及び停止剤の微細分散された混合物を取り出し、かつ相分離に供給する。
イソブテン含有フィードを、組み込まれた循環ポンプが設けられているループ反応器の吸引側に供給した。触媒として三フッ化ホウ素及び助触媒としてイソプロパノールを、別個の流れ中に供給した。反応器を、反応媒体中の温度が−15℃であるように冷却した。(助)触媒量及び反応器中の平均の滞留時間を、以下の表に記載された分子量の低分子量もしくは中分子量のポリイソブテンが得られるように制御した。イソブテン含有フィードとして、一方ではイソブテン約50質量%及びヘキサン50質量%の混合物("純イソブテン")、他方ではイソブテンを含有しているラフィネート1(イソブテン約40%、異なる濃度の1−ブテン、2−ブテン類、n−ブタン及びイソブタン60%)を使用した。
前記の例とは異なり、ダイナミックミキサーの代わりにスタティックミキサー(工業製品SULZER)を使用し、その際に、有機反応相及び停止剤をスタティックミキサーの入口で一緒にし、混合管に沿って分散が進行することによってはじめて反応停止が行われた。停止及び相分離後に取得されるポリマー溶液は、195もしくは287mg/kgの高いフッ素含量を有する。その後の2つの抽出工程後にも、凝集フィルター中での最も微細な小滴分離後に触媒錯体は不完全にのみ分離されることができた。
スタティックミキサーを有し、例4及び5に記載された通りの装置配置中で、平均分子量10 000及び15 000ダルトンを有するポリイソブテンの製造も試験的に調べた。このためには、予め、反応条件(反応温度、反応混合物の組成及び触媒量)を、高い分子量に調節した。反応器排出物は、それぞれのポリマー、残存イソブテン約25%、不活性溶剤約55%及び三フッ化ホウ素錯体からなっていた。得られたポリマーの分散性は約7であった。
例6に相応する反応器排出物を、反応の停止のために、独国特許出願公開(DE-A)第42 20 239号明細書記載のダイナミックミキサーの外周壁中へ、直接供給した。停止剤として使用され、70℃の温度を有する熱い凝縮物を、0.2〜06kg/kgの比で、外周壁中の第二の入口オリフィスを介して供給した。25℃の温度を有し、分散装置から生じた分散液を、相分離装置中で、凝集フィルターを用いて、澄明なポリマー溶液及び水相へ分離した。ポリマーの高い分子量及び高い残存イソブテン含量にもかかわらず、フッ素は、付加的な抽出なしで8〜10mg/kgの残存含量に及び第三級ブタノールは約10mgの残存含量に分離されることができた。例6とは異なり、2.5の低く、ひいては規格に適合した分散性が達成された。
このポリマー溶液は、付加的な抽出工程なしで直接さらに加工されることができる。当該の経験によれば、ポリマー溶液のさらなる後処理の際に、例4及び5の場合のような腐食問題を生じなかった。
