合成了2-(N,N-二羧甲基)氨甲基4-氯酚,进而在水溶液中合成了其铜(Ⅱ)配合物,通过X-射线单晶衍射法测定了晶体结构.配合物中心Cu(Ⅱ)为五配位四方锥结构,在该配合物的晶体结构中存在两种构象异构体,相互问隔通过分子问氢键连接,延伸为一维链状结构.催化性能研究表明该配合物对H<,2>O<,2>的氧化降解聚丙烯酰胺有一定的催化作用,可以使分子量由6.1×10<'6>降低至1.66×10<'5>.%A complex, 2-(N, N-biscarboxymethyl) aminomethyl-4-chloro-phenol Cu( Ⅱ), was synthesized using di-sodium 2-(N,N-biscarboxymethyl) aminomethyl-4-chloro-phenol and CuC12 in water. The crystal structure was characterized by single crystal Xmy diffraction analysis. The result indicates that the copper ion is penta-coordinated. There are two kinds of molecules with different conformation in the crystal, which are fixed by intermolecular hydrogen bonding of carboxyl and phenolic hydroxyl group and form the 1-D supramolecular structure. The result of catalysis study showed that the complex could catalyze the oxidative degradation of PAM by H2O2, and the molar weight can be reduced to 1.66 × 105 from 6. 1 × 106.
