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.
