Versuchsvorschrift

A suspension containing 21.87 g of 2-benzyl-4-chlorophenol, 27.76 g of 1-chloro-2,3-epoxypropane and 27.64 g of potassium carbonate in 200 ml of butanone is refluxed for 12 hours. The inorganic salts formed are filtered off and drained. The solvent and excess 1-chloro-2,3-epoxypropane are evaporated off under vacuum and the residue is distilled at between 160° C. and 180° C. under 0.01 mm of mercury.
