Claims (6)

  1. 첫째 단계에서, 염기성 수용액중에 존재하는 약 90%까지의 아릴보란의 부가물을 최초 pH로 중화시키고, 둘째 단계에서, 용액중에 존재하는 나머지 비중화된 부가물의 적어도 일부를 최초 pH보다 낮은 최종 pH로 중화시켜, 적어도 두 개의 단계에서 부가물을 중화시킴을 특징으로 하여 염기성 수용액에 용해된 부가물로부터 아릴보란을 회수하는 방법.
  2. 제1항에 있어서, 최초 pH를 약 8.0 내지 8.7의 범위에서 유지하고 최종 pH를 약 7.8 내지 7.0의 범위에서 유지하는 방법.
  3. 제1항에 있어서, 최초에 용액에 존재하는 50내지 90%의 부가물을 첫째 단계에서 중화시키는 방법.
  4. 제3항에 있어서, 아릴보란이 트리페닐보란인 방법.
  5. 제3항에 있어서, 부가물이 트리아릴보란의 알카리금속 수산화물 부가물인 방법.
  6. 제5항에 있어서, 부가물이 트리페닐보란의 수산화나트륨 부가물인 방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
