Photochemical Reactions of Unsaturated Fatty Acid Methyl Esters. I.

open access: yesJournal of Japan Oil Chemists' Society, 1971
The photo-dimerization reactions of methyl β-eleostearate were studied. When irradiated with light of high pressure mercury lamp, methyl β-eleostearate was also observed to form the dimer in CCl4 and in CCl3H solutions as well in n-heptane. However, the dimer of the eleostearate obtained by illumination with light in CCl4 or CCl3H was chlorinated.
