Abstract: Gas hold up and reaction effect of autoclave have been determined with different types of stirrers,which shows that the catalytic hydrogenation of rosin is a reaction of external diffusion control on Raney nickel for the purpose of eliminating the influence of external diffusion by using solvent and two layer stirrer with variation of agitation speed,which leads Raney nickel to show similar activity as that of the noble metal Pd/C catalyst.Relation between concentration of reactants and products and reaction time has been traced on line in the course of reaction.Result shows that hydrogenations of abietic acid to abietenoic acid and abietanoic acid are parallel reactions under the reaction condition of 17℃,5.0MPa.

Key words: Raney nickel, rosin, catalytic hydrogenation
