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.

Substituted pyridinesulfonamide compounds or their salts, process for preparing the same, and herbicides containing the same

A substituted pyridinesulfonamide compound or its salt represented by the following general formula (I): wherein R1 is an unsubstituted or substituted alkyl group; R2 is an unsubstituted or substituted alkyl group, or an unsubstituted or substituted alkoxy group; and X and Y are each independently a member selected from the group consisting of alkyl groups and alkoxy groups, is disclosed. This compound is useful as the effective ingredient of a herbicide showing a wide weed-control spectrum even if used in a small amount.
