Abstract
This invention provides the herbicidal active ingredient, a dimethylamine salt crystal of N-phosphonomethyl glycine (glyphosate), its preparation process and a solid formulation containing the crystalline dimethylamine salt of glyphosate as well as its application. Said preparation process comprises adding glyphosate and a suitable amount of solvent into a conventional reactor and introducing a dimethylamine gas for reaction, wherein the reaction temperature is controlled between 5 and 90° C. After the completion of the reaction, the temperature is reduced slowly to a certain value, a crystalline dimethylamine salt of glyphosate is precipitated (or precipitated after a crystal seed is added).
