摘　　要：以废旧聚丙烯纤维为骨架,通过接枝苯乙烯、氯甲基化和负载N-(4-吡啶)哌嗪,合成了高分子(纤维)负载-N-(4-吡啶)哌嗪(1),其结构经IR和元素分析表征,并通过小分子模拟确证。1(5mol%)用于催化1-苯基乙醇的乙酰化反应,收率90%,在多次循环使用后催化活性基本不变。Polymer（fiber）-supported-N-（4-pyridinyl）piperazidine（1） was synthesized by grafting styrene,then chloro-methyl and supported N-（4-pyridinyl）-piperazidine using waste polypropylene fiber as a framework.The structure was characterized by IR and elemental analysis,and was confirmed by small molecular simulation.1 of 5 mol% was used to catalyze acetylation of 1-phenethyl alcohol with acetic anhydride in yield of 90%,and could almost keep the same catalytic activity after 5 recycles.
