摘　　要：研究了稀土氧化物 (NdnOm,SmnOm,GdnOm,LanOm)及其负载型催化剂对松香的催化酯化反应 ,系统探讨了稀土氧化物催化松香酯化的动力学规律 ,并初步比较了稀土及其附载型催化剂的催化性能。Catalytic effect of rare earth metal oxides(Nd nO m,Sm nO m,Gd nO m,La nO m)for rosin esterification had been studied.The dynamic experimental method and the theoretical kinetics equations of the esterification were obtained.Moreover,the activity of rare earth metal oxides and its supported catalysts had been compared.
