Abstract

The potassium salt of alpha-(4-chloro-2-methylphenoxy) propionic acid is prepared by reacting alpha - (4 - chloro - 2 - methylphenoxy) propionic acid and aqueous potassium hydroxide, heating for one hour, partially drying separated solid, suspending in acetone and evaporating to dryness and finally drying in vacuo.ALSO:A weed killing composition in solid or liquid form comprises as active ingredient alpha-(4-chloro-2-methylphenoxy) propionic acid in the form of its potassium salt preferably application of at least 32% W/V calculated free acid.
