改变金属离子种类和高分子配位体的结构可以改变高分子金属催化剂的催化活性。本文作者在SiO_2为载体的聚乙烯醇缩对N,N-二甲氨苯甲醛—钯单金属高分子催化剂中引入少量第二种金属。离子形成混合金属高分子催化剂。研究结果表明,其中Co~(2+),Ni~(2+)及NaAc的引入对原催化剂具有较好的助催化效果,其中Ni~(i+)的引入使原单金属高分子催化剂对丙烯酸的催化加氢活性可提高75％,此外本文还对混合金属高分子催化剂的其他催化性能进行了研究。
Altering the type of metal ions and the structure of the polymer ligands can change the catalytic activity of the polymeric metal catalyst. In this paper, the author introduced a small amount of the second metal into the N, N-dimethylaminobenzaldehyde-palladium monometallic polymer catalyst on the SiO_2 carrier. Ions form mixed metal polymer catalysts. The results showed that the introduction of Co ~ (2 +), Ni ~ (2+) and NaAc had a good promoter effect on the procatalyst. The introduction of Ni ~ (i +) promoted the conversion of the original single metal catalyst The catalytic hydrogenation activity can be increased by 75%. In addition, other catalytic properties of the mixed metal polymer catalyst are also studied.
