摘 要: 红外、可见吸收光谱和差热分析结果表明,环烷酸钴是一个含有二个配位水分子的八面体络台物。它的一个配位水被含酮有机配体取代后,另一个配位水与钴之间的配位键被活化。这种含酮配体环烷酸钴对环己烷的催化氧化是一级反应过程,反应速率决定于催化剂与环己基氢过氧化物的取代反应。它较之环烷酸钴是一种更有前途的催化剂。 According to the results of analysis by infrared absorption spectroscopy,visibleabsorption spectroscopy and differential thermal analysis,naphthenate cobalt is anoctahedral complex compound containing two complexing water molecules.If onewater molecule is replaced by an organic ligand containing ketone,the coordina-ting bond between cobalt and the remaining water molecule will be activated.Thecatalytic oxidation of cyclohexane with naphthenate cobalt containing ketoneligand is a first-order reaction.The rate of the reaction depends on the substitutionreaction of cyclohexyl hydroperoxide with the catalyst.This kind of catalyst hasa brighter future than naphthenate cobalt.
