Method for producing 4-amino-5-chloro-1-phenyl pyridazinone-(6)

In a process for preparing 4-amino-5-chloro-1-phenylpyridazin-6-one by reacting 4,5-dichloro-1-phenylpyridazin-6-one with aqueous ammonia in the presence of a catalyst, the catalyst used is soluble in the aqueous alkaline reaction medium but is essentially insoluble in the reaction medium which has been acidified after removal of the 4-amino-5-chloro-1-phenylpyridazin-6-one. The process of the present invention makes it possible for the catalyst to be recovered and reused in a simple manner.
