摘要
本文以便宜的纤维素为原料,通过膦化,合成了纤维素氧膦配体,与二氯化钯络合,制备了一种纤维素氧膦-钯催化剂。用于催化氢化烯烃,常温常压(H_2)下,比文献中的聚苯乙烯p-pdcl_2有更大的催化氢化活性。认为高分子配体络合的pd(Ⅱ)还原后。催化加氢活性更高。含氧的极性溶剂对催化加氢有显著促进作用。催化剂Ⅰ在奎气中稳定并可重复使用。
A uew polymer bound palladium complex has been prepared by the reactiou of palladium chloride with phos-phinated cellulose. The activity of reductive state palladium complex is higher that activity of polystyrenepd(Ⅱ)cl_2 to catalyze the hyd rogenation of olefins at room temperatare under one atomspheric pressure of hyprogen. Oxygen-containing solvents remarkably promote the catalytic activity. This catalyst was very stable and could be reused.
