Claims (6)
- 연속 대량 결정화의 경우, 특히 접종물질의 첨가에 의한 황산암모늄의 연속 대량 결정화의 경우, 결정 크기를 제어하는 방법에 있어서,- 실제 결정화 공정에는 관계없는 변수들로 접종물질을 제조하고,- 접종물질의 고체의 평균 입자직경이 0.1 내지 1.0 mm이어서 소망하는 결정화물의 것보다 작게 하고,- 접종물질의 고체를 결정화의 주 공정과는 관계없이 여러 공업기술적 부분류로부터 설정된 입자 크기 범위로 생산하고,- 첨가시 접종물질의 온도는 결정화기 내 공정 온도 보다 낮은 40℃까지, 바람직하게는 10 내지 30℃가 되게 하고,- 결정화기 내로의 모든 다른 공급물 및 환류물은 고체가 없게 하는 것을 특징으로 하는 연속 대량 결정화의 경우 결정 크기를 제어하는 방법.
- 제 1 항에 있어서, 불연속적 접종의 경우, 결정화기 내 결정화물의 선정된 단편(부분)의 질량분(질량비율)이 소정된 한계범위 내에 있도록 하는 가운데 접종물질을 불연속적으로 첨가하는 것을 특징으로 하는 연속 대량 결정화의 경우 결정 크기를 제어하는 방법.
- 제 1 항에 있어서, 연속 접종의 경우, 결정화기로부터 인출되는 고체에 대해5 내지 30 중량%, 바람직하게는 7 내지 15 중량%의 양으로 접종물질의 고체분을 첨가하는 것을 특징으로 하는 연속 대량 결정화의 경우 결정 크기를 제어하는 방법.
- 제 1 항 내지 3 항 중의 한 항에 있어서, 접종물질의 고체의 평균 입자직경이 0.3 내지 0.8 mm인 것을 특징으로 하는 연속 대량 결정화의 경우 결정 크기를 제어하는 방법.
- 제 1 항 내지 4 항 중의 한 항에 있어서, 접종물질의 고체의 소망 입자크기가 최종 생성물의 기계적 분쇄에 의해 및/또는 별도의 결정화 단계에서 이루어지는 것을 특징으로 하는 연속 대량 결정화의 경우 결정 크기를 제어하는 방법.
- 제 1 항 내지 5 항 중의 한 항에 있어서, 접종물질이 최종 생성물과 같은 화학적 조성을 갖는 것을 특징으로 하는 연속 대량 결정화의 경우 결정 크기를 제어하는 방법.
