Versuchsvorschrift

Crude tricosene made by the process described in Example I was treated two different ways and distilled under vacuum in order to determine whether isomerization had occurred. The first treatment involved washing with equal volumes of water, and then drying over MgSO4 prior to distillation. This resulted in 30.7% cis and 43.4% trans. In the second treatment, 6.5 l of 4M HCl was added followed by phase separation. The organic phase was then washed with 3 l of saturated sodium bicarbonate solution prior to distillation. This treatment resulted in 39.0% cis and 35.2% trans determined by GC as described above.
