Versuchsvorschrift
The obtained (Z)-11-hexadecenol (Formula II, R=H) is added to a mixture of 5 ml. of dry pyridine and 4 ml. of acetic anhydride, and the mixture is stirred at 0° C. for 3 hours. The solution is poured onto ice and extracted with methylene chloride. The extract is washed with water, 3% aqueous sulfuric acid and again with water, dried over magnesium sulfate, filtered, and the solvent is evaporated. The residue is distilled in fine vacuo. 2.2 g (40%) of (Z)-11-hexadecenyl acetate (Formula I, R=H) are obtained; the product is identical with the substance obtained according to step (A) above.
