cyclohexane

Article contains results of oxidation of different classes of hydrocarbons (alicyclic, alkylaromatic) in the presence of catalytic systems containing salt of variable valence metal and organic additive of different nature (perfluorooxasulphonates, crown-ethers, polyglycols). It was found that the influence of investigated catalytic systems depends on the nature of the hydrocarbon and the nature of the additive. The main areas of influence of organic additives on the rate and selectivity of oxidation of hydrocarbons were considered and the most probable ones were proved.

Influence of individual catalysts – oligomeric chelate complexes of cobalt and copper in the cyclohexane oxidation process was investigated. The method of of metal-complex catalysts synthesis was shown. The influence of complex oligomers and their ligands on the parameters of the cyclohexane oxidation process was analyzed.

Research of the influence of oxygen and nitrogen containing organic additives to the catalyst on the main parameters of the process of cyclohexane oxidation have been conducted. A wide range of nitrogen and oxygen containing compounds and compounds based on polyglycols with varying molecular weight have been used as additives. The obtained results have been analyzed in view of the structural features of the studied additives and the probability of their interaction with the catalyst and intermediate products of oxidation with subsequent formation of intermediate complexes or associates.
