実験手順

46 ml of thionyl chloride were added over 30 minutes to a solution of 130 g of 2,4-dichlorophenoxy-acetic acid in 150 ml of benzene, and the mixture was refluxed for one hour. The solvent and the excess thionyl chloride were eliminated under reduced pressure and the residue was distilled under 0.1 mm of mercury to obtain 91.4 g of the sought product with a boiling point of 120° C. at 0.1 mm of mercury.
