本文介绍从合成气一步合成乙二醇所选用的钴、钌、钌—铑等催化剂的研究情况及其作用机理的研究。在卤化物助催化剂的钌体系中进行CO分子的均相氢化反应,可能形成金属甲酰基络合物中间体。该体系含有一个活泼氧给体和一个具有亲电羰基配体的络合物,故以双分子历程来说明似乎合理。产物的选择性主要取决于金属氢化物的酸强度。 This article describes the synthesis of ethylene glycol from one step synthesis of cobalt, ruthenium, ruthenium - rhodium catalyst research and its mechanism of action. Homogeneous hydrogenation of CO molecules in a ruthenium system of a halide cocatalyst may form a metalformyl complex intermediate. The system, which contains a living donor and a complex with an electrophilic carbonyl ligand, seems to be justified by the bimolecular history. The selectivity of the product depends mainly on the acid strength of the metal hydride.
