Process for the preparation of phenoxypropionic acids and their alkali metal salts

Process for the preparation of (phenoxy- or benzyl-)-phenoxypropionic acids by simultaneous addition of 2-chloropropionic acid (ester) and the double molar amount of an aqueous alkali hydroxide to a solution of a phenoxyphenol or benzylphenol in a solvent forming an azeotropic mixture with water, wh...

Zusammenfassung:	Process for the preparation of (phenoxy- or benzyl-)-phenoxypropionic acids by simultaneous addition of 2-chloropropionic acid (ester) and the double molar amount of an aqueous alkali hydroxide to a solution of a phenoxyphenol or benzylphenol in a solvent forming an azeotropic mixture with water, while continuously distilling off the water formed or introduced.
