丁烯酮-丙烯腈共聚物与过渡金属的配合物催化甲醇羰基化制乙酸和乙酸酐

Copolymer-Transition Metal Complexes for Carbonyltion of Methanol to Acetic Acid and Acetic Anhydride

合成了一系列丁烯酮-丙烯腈共聚物与过渡金属的配位化合物,用X-射线光电子能谱(XPS)研究了其中存在的配位特征。通过甲醇羰基化反应制备乙酸、乙酸酐的反应,考察了不同催化剂的活性。实验结果表明,在反应中其活性顺序:铑配合物>镍配合物>钌配合物>钴配合物。

A series of methyl vinylketone-acrylonitrile copolymers and their complexes with transition metal have been prepared. Structure characteristics of the complexes have been determined by X-ray photodlectron spectroscopy(XPS). The experiments of me-thanol carbonylation to acetic acid and acetic anhydride have rerealed the sequence of catalytic reactivity Rh>Ni>Ru>Co.
