| 摘 要： | 合成了氨基功能化乙烯基咪唑离子液体(AIL),利用氨基固定金纳米粒子以及双键的聚合作用,获得了聚离子液体固载金纳米粒子的催化剂(GNPs-P-AIL).采用红外光谱、紫外-可见光谱和透射电子显微镜等方法对GNPs-P-AIL进行了表征.结果表明,AIL在固定金纳米粒子并聚合后仍然保持着离子液体的基本结构,金纳米粒子分布均匀,粒径为6～8 nm.GNPs-P-AIL催化剂对苯乙烯环氧化具有较好的催化活性,以双氧水为氧化剂,在60℃下反应6 h时,苯乙烯的转化率和环氧苯乙烷的选择性分别可达81.5%和88.3%.

| Abstract: | An amino-functionalized ionic liquid of N-(3-aminopropyl),N(3)-(vinyl)-imidazolium bromide(AIL) was synthesized and used to stabilize gold nanoparticles(GNPs).Further polymerization of the resultant GNP-containing AIL led to a composite catalyst(GNPs-P-AIL) in which GNPs were supported by ionic copolymer.The composite catalyst was characterized by means of Fourier transform infrared spectroscopy,ultraviolet-visible spectroscopy,and transmission electron microscopy.It was found that the structure of ionic li... |
