Versuchsvorschrift

A mixture of 5-chloro-2-hydroxybenzenesulfonic acid, sodium salt (7.9 g), NaOH (1.37 g) and water (25 ml) was heated on a boiling water bath until the mixture became homogeneous. Styreneoxide (2.4 g) was added dropwise over a period of 10 minutes and the mixture was heated with stirring on a boiling water bath for 1 hr. It was extracted with ether and the aqueous solution was evaporated to dryness. The residue was treated with water and the insoluble white precipitate was collected by filtration and washed with 5 mL water to obtain 2-(4-chloro-2-sulfophenoxy)-2-phenylethanol (4.1 g).
