以普通商品聚丙烯腈(PAN)为原料, 合成了四种功能基化的纤维高分子载体, 挑选出其中一种与金属钯盐反应合成出了高分子负载钯催化剂. 利用元素分析、红外光谱、原子吸收光谱、SEM及XPS等手段对其结构进行了表征. 研究了该催化剂对碘代苯与丙烯酸乙酯反应的催化性能及循环使用性能.

关键词: 高分子(纤维), Heck反应, 负载型钯催化剂

Commercially available polyacrylonitrile (PAN) fiber was used as the polymer support material to synthesize a kind of polymer(fiber)-supported palladium catalyst. The structure of this catalyst was con-firmed by elemental analysis, FT-IR, atomic absorption spectrum, SEM and XPS. Its catalytic performance in Heck reaction of iodobenzene with ethyl acrylate was studied

Key words: Heck reaction, polymer(fiber), supported Pd cataly
