An object of the invention is to provide a process for industrially producing fluorinated dicyanobenzenes using tetrachlorodicyanobenzene as a raw material.
According to the present invention, fluorinated dicyanobenzene can be produced in a high yield by allowing tetrachlorodicyanobenzenes to react with a fluorinating agent in the presence of a non-protonic polar solvent in an amount of 0.1 to 3 times by mass based on the tetrachlorodicyanobenzene. Further, the above production can be conducted more efficiently by reacting while disintegrating or removing bulk solid matters.
本发明的目的是提供一种以四氯二氰基苯为原料工业化生产氟化二氰基苯的工艺。
根据本发明,让四氯二氰基苯在非质子极性溶剂存在下与氟化剂反应,可以高产率生产氟化二氰苯,反应量为四氯二氰苯质量的 0.1 至 3 倍。此外,通过在分解或去除块状固体物质的同时进行反应,可以更有效地进行上述生产。
