Versuchsvorschrift

Distearyl ether was synthesized by reacting stearyl bromide (Sigma) with PEG-900 in the presence of potassium hydroxide. Stearyl bromide (4.168 g in 10 ml toluene) was slowly added with stirring to 4.64 g of PEG-900 in 10 ml of toluene at 45° C. The mixture was then stirred at 60° C. for 30 min. and refluxed for 6 hrs. The final product was treated with charcoal, filtered and isolated from toluene.
