摘要

improvement in the production process of glyphosate monoammonium salt, a solid active ingredient soluble in water of high concentration and agricultural treatment process. the present invention deals with an improved process for obtaining the glyphosate monoammonium salt, a water-soluble solid active ingredient with high concentration for use as a crop protection product. more specifically, the present invention relates to a process for producing the monoammonium salt of the solid n-phosphonomethyl glycine of the formula [hoocch2nhch2po (oh) 2] .nh3 with high levels of purity 95%, having as the principle the reaction in a solid / solid system by pyrolysis of a solid ammonium salt and / or urea with the solid acid glyphosate. the product of this reaction has adequate water solubility and can be used directly as an agricultural pesticide or as an ingredient in the preparation of compositions containing glyphosate salts in various combinations of adjuvants.
