    • A method for efficiently extracting a reaction product containing a target aromatic fluorine compound formed by the halogen exchange reaction of an aromatic chlorine compound with a fluorinating agent quickly from the reaction vessel without suffering part of the reaction product to remain as a residue inside the reaction vessel is disclosed. Specifically, the reaction product is extracted from the reactor subsequently to the halogen exchange reaction at a temperature in the range of 20-250° C. By this method, the reaction product formed in consequence of the halogen exchange reaction can be efficiently extracted quickly from the reaction vessel, and that without suffering occurrence of a residue of the reaction product.
    • 通过芳族氯化合物与氟化剂的卤素交换反应形成的目标芳香族氟化合物的反应产物从反应容器中快速提取而不会产生部分反应产物残留在反应容器内部的方法 被披露。 具体地说,在20-250℃的温度下,从反应器中抽出反应产物进行卤素交换反应。通过这种方法,由于卤素交换反应而形成的反应产物可以从 反应容器,并且不会发生反应产物的残留物。
