摘要： A process for preparing a dry pesticidal composition including a glyphosate component comprising a water-soluble salt of glyphosate acid, a dicarboxylate component and optionally an adjuvant component. According to the process of the present invention, a glyphosate component is combined with a dicarboxylate component and optionally an adjuvant component to form an enhanced pesticidal composition. The glyphosate component and/or the dicarboxylate component may be combined in their salt form or either or both may be combined in acid form and reacted in the mixture with a base component to form the corresponding salt.

摘要： A process is provided for preparing a downstream processable ammonium glyphosate paste. The process includes mixing in a reactor (i) particulate glyphosate acid, (ii) ammonia, (iii) adjuvant, and (iii) water. The reaction of glyphosate acid with ammonia causes the generation of heat resulting in the partial evaporation of the water such that an ammonium glyphosate paste is formed, having a moisture content of about 2% to about 20% by weight. The addition of the adjuvant to the reactor (i) increases the rate at which the glyphosate acid and ammonia react to form ammonium glyphosate and/or (ii) reduces the flow resistance of the reaction mass as it is being conveyed to the product discharge region of the reactor. The ammonium glyphosate paste may then be further processed to form a granular herbicidal composition.

摘要： A process is provided for preparing a downstream processable ammonium glyphosate paste, comprising mixing in a suitable vessel (i) particulate glyphosate acid, (ii) ammonia in an amount of about 0.8 to about 1.25 moles per mole of the glyphosate acid, and (iii) water in an amount of about 10% to about 25% by weight of all materials being mixed in the vessel, thereby causing a reaction of the glyphosate acid and ammonia that generates heat causing partial evaporation of the water, and forms an ammonium glyphosate paste having a moisture content of about 5% to about 20% by weight. A process is also provided for preparing a dry granular herbicidal composition, comprising (a) forming an ammonium glyphosate paste as described above and thereafter, if the moisture content of the paste is greater than about 15% by weight, applying heat and/or vacuum to reduce the moisture content to about 5% to about 15% by weight; (b) thereafter adding to the paste, with mixing, one or more surfactants in a weight ratio of total surfactant to ammonium glyphosate of about 1:9 to about 1:3 to form an extrudable wet mix; (c) extruding the wet mix to form extrudate strands that break to form moist coherent granules; and (d) drying the granules to produce the dry granular composition.
