范文编号:CL063 范文字数:9092,页数:26 摘 要:本文分别以水杨醛和1-甲酰基-2-萘酚为原料合成水杨醛类镍配合物,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测试了配合物的热性能。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:水杨醛;1-甲酰基-2-萘酚;丙烯齐聚 Abstract:Two salicylaldehyde Ni(Ⅱ) complexes was synthesized from salicylaldehyde and 1-CHO-2-Naphthenol separately,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. 目 录 水杨醛类镍配合物的合成与表征相关范文 |
