Capillary gas‐liquid chromatography of the product formed by sulfuric acid‐catalyzed dimerization of abietic acid showed the presence of some 40 dimeric components. The three major components were isolated and shown to be heptacyclic dimers, two of which had a conjugated double bond system. The other component had two nonconjugated double bonds. Also isolated were three dimers consisting of monomers attached through a single carbon‐carbon bond: one carboxyl group in each of these dimers was in the form of a γ‐lactone.
