METHOD FOR PRODUCING DISPROPORTIONATED ROSIN

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a disproportionated rosin comprising converting all of the abietane skeletons to dehydroabietic acid and tetrahydroabietic acid. SOLUTION: This method for producing a disproportionated rosin is characterized by comprising disproportionating a rosin using a hydroxyapatite-based catalyst.
