Abstract: Pd/BC was used as catalyst for disproportionation of slash pine rosin. The optimal reaction condition was established. The amount of catalyst is 0.4% of raw material by mass, stirring speed is 500 r/min,reaction temperature is 270℃ and the reaction time is 3 h. In these conditions, the content of dehydroabietic acid in slash pine disproportionated rosin is above 56% and abietic acid is decreased to 2%. But this doesn’t meet the national standard (the content of abietic acid ≤0.5%). Pd/BC also catalyzes disproportionation reaction of masson pine rosin in the same conditions above, except that the catalyst amount is 0.3%. The content of abietic acid in masson pine disproportionated rosin is 0.43%, which meets the national standard.
Key words: palladium/bamboo-charcoal (Pd/BC), slash pine rosin, disproportionation reaction
