范文编号:CL069 范文字数:8554,页数:23 摘要:本范文以2-羟基-1-萘甲醛和邻甲基苯胺为原料合成2-羟基-1-萘甲醛亚胺镍配合物,以及苯胺和二水杨醛二水镍配合物合成二水杨醛亚胺镍配合物,作为丙烯二聚催化剂。用红外图谱与紫外光谱表征配合物的结构。用DSC测试配合物的热性能。通过紫外光谱研究了配合物/三苯基膦溶液体系的性质,推测催化活性中心形成的可能机理。
关键词:邻甲基苯胺;2-羟基-1-萘甲醛;苯胺 Abstract: The 2-hydroxy-1-naphthalene formaldehyde imine nickel complexes is synthesized from 2-hydroxy-1-naphthalene formaldehyde and o-toluidin,and then bis(substituted-salicylaldimene)Ni(Ⅱ) complexes is prepared from aniline and bis(salicylaldehyde)Ni(Ⅱ), these two complexes can be used as catalyst for propylene dimerization. The complexes were characterized by IR and UV spectrum. The thermal properties of complexes were determined by DSC .The properties of complexes /triphenylphosphine solution system were investigated UV method, and then the plausible formation mechanism of catalytic active site was deduced. Key words: o-toluidine; 2 - hydroxy -1 - naphthalene formaldehyde; aniline 目录
