In order to prepare polymer supported palladium catalysts for selective hydrogenation, three kinds of palladium salts with different anions [Pd(OAc)2 PdCI2 .PdI2] were reacted with Poly --N, N - dimethyl - 4 - vinylbenzyl - amine and then the formed polymeric complexes were reduced by CH3OH-NaOH. The influence of anions in the initial palladium salts on the size, dispersion degree of the palladium particles as well as the hydrogenation properties of the synthesized polymer supported palladium catalysts...

In order to prepare polymer supported palladium catalysts for selective hydrogenation, three kinds of palladium salts with different anions [Pd(OAc)2 PdCI2 .PdI2] were reacted with Poly --N, N - dimethyl - 4 - vinylbenzyl - amine and then the formed polymeric complexes were reduced by CH3OH-NaOH. The influence of anions in the initial palladium salts on the size, dispersion degree of the palladium particles as well as the hydrogenation properties of the synthesized polymer supported palladium catalysts were examined. Experimental results showed that the polymeric catalyst prepared from Pd(OAc)2 possesses the highest hydrogenation activity,selectivity and lifetime.

Surface reaction infrared dynamic technique was used to examine the CO adsorption and the hydrogenation properties over promoted rhodium catalyst,Rh Ag/SiO 2. The result indicated that reactivity of the linear CO with hydrogen was higher than that of the bridged CO,and that the linear CO was the major active adsorbed species in the hydrogenation. Increase in temperature favored increase in the intensity ratio of linear to bridged CO bands on Rh Ag/SiO 2. Some C 1 2 oxygenated intermediates,...

Surface reaction infrared dynamic technique was used to examine the CO adsorption and the hydrogenation properties over promoted rhodium catalyst,Rh Ag/SiO 2. The result indicated that reactivity of the linear CO with hydrogen was higher than that of the bridged CO,and that the linear CO was the major active adsorbed species in the hydrogenation. Increase in temperature favored increase in the intensity ratio of linear to bridged CO bands on Rh Ag/SiO 2. Some C 1 2 oxygenated intermediates, such as surface formyl, formate,acetyl, acetate, ketene and enolate,appeared in the surface reaction. Addition of promoter Ag was in favor of increasing the linear to bridged intensity ratio of the CO adsorption state,and thus the rates of CO hydrogenation and the formation of C 2 oxygenate on the Rh catalyst.
