Description
Mb[M1(CN)r(X)t]c[M2(X)6]d・nM3 xAy
によって表すことができ、式中、MおよびM3は各々金属であり、M1はMとは異なる遷移金属であり、各XはM1イオンと配位するシアン化物以外の基を表し、M2は遷移金属であり;Aはアニオンを表し、b、c、およびdは静電的に中性の錯体をもたらす数字であり、rは4〜6であり、tは0〜2であり、xおよびyは金属塩M3 xAyの電荷を平衡させる整数であり、nはゼロまたは正の整数である。上記の式は、DMC触媒錯体中にしばしば存在するt−ブタノール等の中性錯化剤の存在をもたらさない。
アルキレン重合を、長さ200メートルの管状反応器中で行う。ポートは、アルキレンオキシドをそれらを通して選択的に供給できるように設計してあるため、アルキレンオキシドは反応器の長さに沿って所定のところに供給することができる。
実施例2〜4では、実施例1に記載の管状反応器での3つの異なるポリエーテルポリオールの製造を例示する。開始剤化合物、流量、滞留時間、およびアルキレンオキシドを選択することによって異なる生成物が作製される。
