Description
CaはMgよりClとの親和力が強く、原理的にはTiCl4の還元剤に適している。 特に、特許文献3に記載された方法では、Caを溶融CaCl2中に溶解させて使用するが、このように、溶融CaCl2中でのCa還元反応を利用すれば、クロール法のように反応容器内の還元剤の液面にTiCl4を供給する場合と比べて反応の生じる領域(反応場)が拡がり、発熱領域も拡がるので、冷却が容易になる。従って、TiCl4の供給速度を大幅に高めることができ、生産性の向上が期待できる。
陰極: Ca2++2e-→Ca ・・(3)
TiCl4の還元に消費されるCaを電気分解で生成するCaで補充する方法は、還元と電気分解をそれぞれ還元槽と電解槽で行わせ、両槽間で溶融CaCl2を循環させることによっても可能である。しかし、電気分解で陰極側に生成するCaと反応するように、TiCl4を反応槽内の溶融CaCl2中に供給してやれば、反応槽が還元槽と電解槽を兼ねることとなり、両槽を設ける必要がなく、還元槽と電解槽の間で溶融CaCl2を循環させる場合と比べて設備コストなどの面でも非常に有利となる。
