本文应用具有强含氧酸基团或弱含氧酸基的线型高分子,组成强-强、强-弱、弱-弱三种类型复合高分子-钯络合物,测定其对加氢反应的催化活性。结果表明,复合高分子络合物的催化活性一般都好于只含单一高分子的活性,尤其是强一弱型复合高分子络合物,最好的活性约高四倍;改变络合物中两组分配位基团的摩尔之比对催化速度的影响是很相似的,速度与摩尔比曲线都呈现“双峰结构”的特征。此外,本文还讨论了催化性能与其组分高分子的组成、结构、配位基团性质之间的关系以及催化机理。
In this paper, linear polymers with strong oxyacid groups or weakly oxoacid groups were used to form three types of complexes: strong-strong, strong-weak, weak-weak. Catalytic activity of the reaction. The results showed that the catalytic activity of the composite polymer complexes is generally better than that of a single polymer, especially the strong one weak complex polymer complexes, the best activity about four times higher; change the complex The effect of molar ratio of the two groups on the catalytic rate is very similar, and both the velocity and the molar ratio show the characteristic of “bimodal structure”. In addition, this paper also discussed the relationship between the catalytic performance and the composition, structure, coordination group properties and the catalytic mechanism of the polymer.
