Method for producing a solid herbicide formulation

The invention relates to a method for producing a solid herbicide formulation containing a) a herbicide from the group of sulfonylurea, or the salts thereof which are useful in the agricultural domain, b) optionally at least one other herbicide, c) optionally a safener, and d) at least one formulation adjuvant. A suspension is formed in water, consisting of the sulfonylurea a), optionally at least one other herbicide b), optionally a safener c) and at least one formulation adjuvant d). The suspension is adjusted to a pH value between 6.5 and 8 by adding an acid or a base, and is then dried to obtain the solid formulation.

Process of producing sulfonylurea derivatives

This invention relates to a process for producing a compound of the formula (I) as shown below. STR1 wherein Q is a condensed heterocyclic group having a nitrogen atom in the bridgehead position which may optionally be substituted, R1 and R2 each are an alkyl group, an alkoxy group or halogen and Z is CH or N, or a salt thereof. The compound (I) or a salt thereof is novel and of value as agricultural chemicals. According to the process of this invention the compound (I) or a salt thereof can be produced in good yield and high purity.
