Procedimiento

In a stirred 10 liter round-bottom flask equipped with a water cooled condenser, thermometer, nitrogen blanket and equilibrating dropping funnel, was charged 500 grams of Solution 1 and 968 grams of water. With stirring, 2409 grams of glyphosate acid in the form of wet cake were added. Then 1623 grams of 25% aqueous ammonia were added at such a rate that the temperature of reaction mixture did not exceed 85° C. The pH of the reaction mixture was measured, and up to 85 grams of 25% aqueous ammonia were added in increments until a pH of 6.3-6.7 was obtained. The assay was determined by high pressure liquid chromatography by standard methods and sufficient additional water added to give an ammonium glyphosate solution with a glyphosate assay of 41.7% a.e. or 525 g a.e./l.
