Abstract
Summary1. The cis- and trans-modifications of 7-, 8-, and 11-octadecenoic acids were synthesized by methods which leave no doubt as to their structure.2. Many new compounds have been reported including 7-octadecynoic acid, 8-octadecynoic acid. 7,8-diketostearic acid, 8,9-diketostearic acid, cis- and trans-7-octadecenoic acids and their 7,8-dihydroxystearic acid derivatives, and cis- and trans-8-octadecenoic acid derivatives and their 8,9-dihydroxystearic acid derivatives.3. A new series of intermediate reaction products has been reported although these compounds were not fully characterized. These compounds include hexamethylene bromochloride, hexamethylene iodochloride, 1-chloro-6-heptadecyne, and 1-chloro-7-heptadecyne.4. The extinction coefficients at 10.36 microns of the cis and trans-6-, 7-, 8-, 9-, and 11-octadecenoic acids have been calculated and compared.5. The melting points of the cis- and trans-octadecenoic acids and their dihydroxy derivatives were shown to exhibit alternating patterns.
