摘要：Changes in the composition of gum rosin during disproportionation in the presence of 5% palladium-on-charcoal have been determined by gas chromatography. The principal reaction product was dehydroabietic acid. The exocyclic vinyl group of the pimaric/isopimaric-type resin acids was hydrogenated completely. Only a small amount of dihydroabietic acids was formed. Eight dihydro resin acids were identified. No tetrahydro resin acids were observed. ? 1985, Taylor & Francis Group, LLC. All rights reserved.
