Reaktionsschritte
said abietic acid at 200–300° C. for 1–5 hours with the catalyst of 0.1–5% (wt) of 5%–10% palladium/carbon, or incubating directly at 220–380° C. After incubation and cooling down, adding 0.5 to 10-fold (volume) solvent, said solvent can be any one of methanol, ethanol, propenol, acetyester acetic acid, benzene and methbenzene, keeping refluxed for 1–3 hours, filtering when it is warm, cooling down, allowing it to stand for overnight and be crystallized. Dehydroabietic acid is obtained after filtering.
