The production of DOD is unique in that it involves a hydroxylation at two positions and a rearrangement of the double bond of the substrate molecule. The new multifunctional, long-chain aliphatic acid has potential utility as a plasticizer and as a source of intermediates in the synthesis of specialty chemicals.
