Versuchsvorschrift

(Z,Z,E)-1,1-Diethoxy-7,11,13-hexadecatriene (49.36 g, 0.16 mol) and toluene (30 g) were placed in a reaction vessel and stirred at 20 to 25° C. for 30 minutes. After stirring, 10% by weight hydrochloric acid (19.3 g) was added dropwise to the reaction mixture at 20 to 25° C., and stirred for one hour. The reaction mixture was separated into phases. Then, the organic phase was washed with an aqueous sodium bicarbonate solution, and concentrated by removal of the solvent under reduced pressure to obtain (Z,Z,E)-7,11,13-hexadecatrienal (30.47 g, 0.13 mol) with a yield of 82.7%.
