A new technology research on separation and purification of dehydroabietic acid was studied with the raw material of disproportionated rosin. The optimum condition was that:the ratio of dispropor-tionated rosin and 90% ethanol was 0. 4 g/mL, reaction time was 20 min, reaction temperature was 65 ℃,50% and 75% ethanol-water solvent was used for recrystallization four times and three times, the yield of dehydroabietic acid was 16 . 9% and the purity was 98 . 9%.
