  • Patent number: 8492309
    Abstract: A process for preparing an aqueous concentrate glyphosate salt composition comprises (i) neutralizing glyphosate acid with potassium hydroxide and a minor amount of a low molecular weight organic amine in presence of water to produce a glyphosate salt solution having a pH of about 4.8 to about 5.0, where the neutralizing operation comprises a first neutralization step in which a slurry or glyphosate salt solution having a pH of about 4.4 to about 4.7 is produced and a second neutralization step in which the pH is adjusted to about 4.8 to about 5.0; and (ii) after the first neutralization step and before, during or after the second neutralization step, adding further water if necessary and optionally at least one surfactant to produce a final composition having a total glyphosate a.e. concentration not less than about 360 g/l.

  • Patent number: 8236731
    Abstract: A herbicidal composition comprises an aqueous solution of one to a plurality of salts of glyphosate at a total glyphosate a.e. concentration not less than about 360 g/l, wherein (a) said glyphosate is in anionic form accompanied by low molecular weight non-amphiphilic cations in a total molar amount of about 110% to about 120% of the molar amount of said glyphosate; and (b) a major amount to substantially all of the low molecular weight non-amphiphilic cations are potassium cations. The composition exhibits improved tank-mix compatibility with a phenoxy-type herbicide salt formulation by comparison with an otherwise similar composition having a lower molar amount of said low molecular weight non-amphiphilic cations.
