Abstract: The reaction of disproportionation of gum rosin catalyzed by AH nonnoble metal catalyst was studied, and the effects of reaction temperature, reaction time, particle size of catalyst, and stir speed were investigated. It was found that the reaction was of the first order at 240-270℃. Reaction rate constants were 2.9×10-3, 3.1×10-3, 1.42×10-2, 2.51×10-2min-1 at 240, 250, 260 and 270 ℃,respectively. Apparent activation energy E was 184.80×103kJ/mol, frequency factor A was 1.453×1016.
