HYDRATE OF SULFONYLUREA COMPOUND, PROCESS FOR PRODUCING THE SAME AND SUSPENSION FORMULATION CONTAINING THE SAME

摘要

PURPOSE: A sulfonyl urea compound hydrate with an herbicidal effect and a suspension formulation containing the same are provided to prevent the increasing of solid particles and to ensure safety. CONSTITUTION: A sulfonyl urea compound hydrate is denoted by chemical formula I. The hydrate is a semihydrate. A suspension formulation contains the hydrate, thickening agent, surfactant, agrochemical additive, and water. The hydrate is a mixture of sulfonyl urea compounds with non-hydrate. The sulfonyl urea compound is prepared by mixing the sulfonyl urea compound non-hydrate and water and stirring the mixture. The hydrate is prepared by dissolving the non-hydrate in a hydrous organic solvent and crystallizing the mixture.
