Claims (5)
- 비스페놀 A와 페놀의 부가물을 비스페놀 A의 페놀 용액으로부터 물의 존재하에 정출시키는 방법에 있어서, 용액의 밀도 측정에 의거한 피드백 제어에 의해 그 용액중의 페놀의 일부를 제거하거나, 또는 그 용액중에 페놀을 첨가하여 그 용액중의 비스페놀 A의 농도를 조절하고, 조절된 용액을 정석기에 공급하고, 그 정석기에 내벽면의 온도를 내용물 용액의 온도보다 높으나 온도차가 5℃ 이하가 되도록 유지하는 것을 특징으로 하는 비스페놀 A와 페놀의 부가물의 정출방법.
- 제 1 항에 있어서, 상기 조절된 용액중의 비스페놀 A의 농도가 20-50중량%인 비스페놀 A와 페놀의 부가물의 정출방법.
- 제 1 항에 있어서, 상기 조절된 용액중의 비스페놀 A의 농도가 30-45중량%인 비스페놀 A와 페놀의 부가물의 정출방법.
- 제 1 항에 있어서, 정석기내의 내용물 용액의 온도가 35-70℃인 비스페놀 A와 페놀의 부가물의 정출방법.
- 제 1 항에 있어서, 정석기가 드래프트 튜브 타입이며, 그 내벽면의 일부가 드래프트 튜브 벽면인 비스페놀 A와 페놀의 부가물의 정출방법.
