ABSTRACT

The isomerization of methyl linoleate by heating with palladium on carbon catalyst gave an initial rapid rise in the degree of conjugation which reached a maximum and then gradually decreased. The maximum conjugation obtained was about 24% after 4 hrs. of heating at 200±5°C. with 25% by weight of catalyst. Ultraviolet absorption spectra did not indicate the presence of any cyclized aromatic components even after 46 hrs. of heating at 200°C. but showed the formation of aromatics at 250°C. The limit of conjugation obtained is a result of random migration of the olefinic bonds rather than dimerization or polymerization reactions. More... »
