木质素负载钯催化剂的制备及对Heck反应的催化性能

Preparation of Lignin Supported Palladium Catalyst and Its Catalytic Properties for Heck Reaction

以天然木质素和PdC l2为原料,合成了木质素负载钯催化剂,用IR、XPS、TG、DTA等对其进行了表征.研究表明,该催化剂在空气氛围中能催化丙烯酸与芳基碘的Heck反应,并有一定的重复使用性能.

Lignin supported palladium catalyst was prepared and characterized by IR, XPS, TG, DTA. The catalyst was applied as a heterogeneous catalyst for Heck reaction of acrylic acid with aryl iodide. It was found that the Heck reaction could be catalyzed by the catalyst at atmospheric condition. The catalyst could be reused for three times without remarkable decrease in activity.
