The complex of Bis(2,4 pentanedionato) Cobalt has been synthesized.The structure has been characterized by infrared spectra and element analysis.The catalytic activity of the complex in the cyclohexene allylic oxidation by oxygen molecule has been studied.The influences of reaction temperature,time,solvents and additives on the oxidation have been determined.The results show that when the oxidation is carried out under the reaction conditions of 70～80℃,4～10h and 2.0Mpa/O 2,the main product is cyclohexene 2 one.The conversion of cyclohexene increases with the rise of the reaction temperature,time and polarity of solvent.Some additives,such as imidazole,could improve the selectivity of cyclohexene 2 one.
The catalytic performance of catalyst,which was formed in situ from RuCl3-TPPTS[TPPTS:P（m-C6H4SO3Na）3],for slelctive hydrogenation of carbon-carbon double bond in acrylonitrile to prepare propionitrile were studied in biphasic system （aqueous/organic phase）.Good conversion and excellent selectivity were obtained.We studied the effect of KOH/Ru（molar ratio）,H2 pressure,P/Ru（molar ratio）,concentration of Ruthenium,temperature and reaction time on the catalytic activity and selectvity.The results show that the catalytic system have good conversion and very high slectivity for the hydrogenation of carbon-carbon double bond of acrylonitrile at the same time,the catalyst were separated readily from the product.
