Vorschrift

Sodium (44 g, 1.92 mol) was added in small portions to 1.5 liter of absolute ethanol containing 217 g (1.75 mol) of thiocresol, with stirring, uinder nitrogen. After the addition was completed, 640 g (1.92 mol) of bromooctadecane was added, and the mixture was heated at reflux for 2 hours. The hot reaction mixture was filtered, and the ethanol was removed under reduced pressure. The residue was crystallized from heptane yielding 595 g (91%) of white crystals. mp 54°-55° C.
