Methyl octadecenoates are formed by thermal reaction of methyl linoleate in the presence of iodine. For the purpose of clarification of hydrogen source required for the formation of octadecenoates, quantitative relationship of reaction products was studied by the methods of fractional distillation, mass spectral and GLC analyses, and of the measurement of UV spectra of the reaction products after hydrogenation.
The results showed that hydrogen iodide evolved by the action of iodine on Diels-Alder adduct type dimers makes an important role as hydrogen source for the formation of octadecenoates.
