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.
本发明公开了一种方法,用于从反应容器中快速提取由芳香族
氯化合物与
氟化剂的卤素交换反应形成的含有目标芳香族
氟化合物的反应产物,而不会使部分反应产物作为残留物留在反应容器中。具体地说,反应产物是在卤素交换反应之后,在 20-250°C 的温度范围内从反应器中提取出来的。通过这种方法,可以有效地从反应容器中快速提取卤素交换反应生成的反应产物,而且不会出现反应产物残留的情况。
