METHOD FOR PREPARATION OF AN AQUEOUS GLYPHOSATE CONCENTRATE |
| 摘要 |
A method for preparing an aqueous mixture of glyphosate salts to improve the handling of the mixture, the method comprising forming a homogeneous mixture of at least two bases comprising at least one alkali metal hydroxide, and at least one further base selected from alkali metal hydroxides and nitrogen bases and reacting the mixture of the at least two bases with glyphosate acid in an aqueous reaction medium to provide an aqueous mixture of glyphosate salts wherein the concentration of glyphosate (based on glyphosate acid equivalent) is at least 200 gae/L. |

1. A method for preparing an aqueous concentrate mixture comprising salts of glyphosate and at least one other acid herbicide to improve the handling of the mixture, the method comprising:
forming a homogeneous mixture of at least two bases comprising at least one alkali metal hydroxide, and at least one further base selected from alkali metal hydroxides and nitrogen bases, forming a mixture of at least one other acid herbicide with glyphosate acid; and reacting the mixture of the at least two bases with the mixture of glyphosate acid and at least one other acid herbicide in an aqueous reaction medium to provide an aqueous mixture of herbicide salts, wherein the concentration of glyphosate (based on glyphosate acid equivalent) is at least 200 gae/L and wherein the total acid herbicide salts, including glyphosate is at least 360 gae/L and the mole ratio of total alkali metal hydroxides and nitrogen bases:total acid herbicides is in the range of 0.9:1 to 1.3:1. |
