Cyclohexane Oxidation in the Presence of Variable Valency Metals Chelates

Abstract

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.

Influence of Complex-Creative Additives on Oxidation of Hydrocarbons

“…The evidence that the effect of the studied organic additives can not be explained exclusively by their surface activity and effects on mass transition processes (such as increasing the concentration of dissolved oxygen), is that for solutions of cobalt naphthenate and cobalt catalytic system naphthenate-polyglycols in cyclohexanone changes in IR and UV spectra are observed, which clearly show the formation of complexes between the VVM salt and an organic additive [15]. Therefore, we can assume that in the presence of the studied catalytic systems the share of moderate form of transformations that occur in the coordination sphere of the VVM metal ion significantly increases, which leads to a change in selectivity of formation of aimed products and to some deceleration of hydrocarbons oxidation rate in the presence of catalytic systems containing crown-ethers and polyglycols.…”

Use of Chromoxane in the Oxidation of Cyclohexane

“…В науковій літературі наводять інформацію про дослідження можливості застосування хромоксану в складі бінарного каталізатора для гомогенного окиснення етилбензолу [3]. Також є відомості про застосування хромоксану для ініціювання каталізаторів окиснення циклогексану [4].…”

Creating the Basis of Non-Exhaustive Technology of Cyclohexan Oxidation

“…One of the methods of use of acids is to obtain acid esters by their esterification with alcohol [2,4,[5][6][7][8][9]13]. Subsequently, the esters obtained can be used as plasticizers for polymers.…”
