nitrogen-containing triolefinic macrocycle on the periphery (G2-M) was synthesized. The bimetallic Rhodium (III)/Palladium (II) (Rh3+/Pd2+) dendrimer-stabilized catalysts (G2-M(Rh3+xPd2+10-x)) were prepared by a co-complexation route within G2-M and analyzed by 1H NMR, XRD and XPS. The catalytic activity, selectivity and separation capability for the hydrogenation of nitrile-butadiene rubber (NBR) catalyzed
合成了一种新的杂化第二代聚(丙烯亚胺)树枝状聚合物,其末端(G2-M)被含氮三烯大环终止。通过在其中的共络合路线制备了双金属铑(III)/钯(II)(Rh 3+ / Pd 2+)树枝状聚合物稳定的催化剂(G2-M(Rh 3+ x Pd 2+ 10-x))。 G2-M,并通过1 H NMR,XRD和XPS分析。研究了由G2-M(Rh 3+ x Pd 2+ 10-x)催化的丁腈橡胶(NBR)加氢的催化活性,选择性和分离能力。Rh 3+的双金属离子作为新型催化剂体系和Pd 2+影响了对NBR的氢化,其可以与铑的缺电子效应的催化活性3+选自Rh的相互作用而产生3+和Pd 2+内G2-M。
