For example, 5-hexenoic acid or an ester of 5-hexenoic acid (e.g. methyl 5-hexenoate, ethyl 5-hexenoate, etc . . . ) could be used instead of 1-hexene, but the synthesis would entail a reduction of a carboxylic acid or an ester to an alcohol followed by acetylation. These syntheses are respectively shown in FIGS. 12 and 13. With reference to FIGS. 12 and 13, the 5-hexenoic acid or 5-hexenoate is reacted with 5-decene to form 5-decenoic acid or 5-decenoate, respectively, in the presence of Catalyst 823 and under vacuum. The resulting 5-decenoic acid or 5-decenoate is reduced and acetylated to form 5-decenyl acetate. In addition, synthesizing 5-decenoic acid has advantages because the salt of 5-decenoic acid can be recrystallized to increase the trans-isomer to greater than 90 percent trans-5-decenoic acid, which is then reduced and acetylated to greater than 90 percent trans-5-decenyl acetate.
