摘要
钯催化作用下合成的2-炔基芳烃的低基化反应活性分析是保证有色金属纯度和品质的重要指标。通过钯催化作用提高2-炔基芳烃的基化反应活性,研究钯杂多酸催化对2-炔基芳烃的基化反应活性的影响,改善有色金属的冶炼和催化过程。钯催化作用下2-炔基芳烃锚定4-氨丙基-五乙炔,具有较好的催化活性性能,实现金属氧簇外围抗衡离子的稳定,高于传统催化剂的16%,在有色金属冶炼和催化中具有较好的应用价值。
The analysis of the low basic reactive activity of 2- - based on the synthesis of palladium catalyst is an important index to ensure the purity and quality of the nonferrous metals. Via palladium catalysis to improve the - alkynyl arene alkylation reaction activity of palladium catalyzed by heteropoly acid of 2 - alkynyl arene alkylation reaction of active effect on improving the non-ferrous metal smelting and catalytic processes. The catalytic activity of 2- 4-, which has a good catalytic activity, has a good catalytic activity. The stability of the outer counter ions of the metal oxygen cluster is higher than that of the conventional catalyst, which has good application value in the non- ferrous metal smelting and catalysis.
