“…We prepared a manganese-immobilized polymer catalyst [22,23] for the oxidation of nheptane. The catalytic activity and recyclability of Mn polymer complexes were determined taking into account the partial characteristics of the components of the n-heptane oxidation reaction according to the procedure described in [24,25].…”

Catalysts with manganese nanoparticles (5 and 10 wt %) immobilized on poly-4-vinylpyridine were prepared. When interacting with molecular oxygen, the catalyst forms active oxygen, which is involved in the low-temperature oxidation of n-heptane. These catalyst compositions have been used to oxidize n-heptane with pure oxygen to give alcohols, aldehydes and ketones. Oxidation of n-heptane was carried out in the temperature range 303-383 K, molar ratios of heptane:oxygen = 1:3.38, and at atmospheric pressure. It has been found that the non-crosslinked (MnP4VP polymer poly-4-vinylpyridine) and N,N-methylene-bis-acrylamide-crosslinked MnP4VP/MBAA metal-polymer catalyst containing 5 wt % Mn2+ exhibits the highest activity in n-heptane oxidation reactions. The kinetic parameters of the reaction of n-heptane oxidation with oxygen at low temperatures were studied using a kinetic model based on the heptane conversion data. The kinetic model was compiled on the basis of experimental data: heptane:oxygen = 1:3.38 at atmospheric pressure using Mn (wt. 5%) P4VP/MBAA in the temperature range 303-383 K. Within the framework of the chosen kinetic model effective rate constants of the oxidation reaction with the formation of alcohols was calculated

“…Nanocatalysts are also considered as an alternative to known catalysts and show good activity because nanoparticles have a high surface/volume ratio, which increases their activity and selectivity [10]. In the process of immobilization, the surface of metal nanoparticles is modified by functional groups, which increases the focus on nanoparticle catalysts [11][12][13]. Poly (vinylpyridine) (PVP) is used to make such complex catalysts (systems).…”

Oxidation of n-octane was carried out in a stationary reactor using immobilized manganese nanoparticles in various mass percentages (5 and 10 wt.%) on poly(4-vinylpyridine). It was found that manganese-containing catalysts immobilized in polymer are more active in the oxidation of n-octane than similar homogeneous catalysts. A kinetic model and an equation for calculating the oxidation of n-octane in the presence of a manganese-polymer catalyst were chosen for the calculation. Taking into account the kinetic model, the velocity constant of the specified process is calculated. A high conversion in the oxidation reaction of n-octane with molecular oxygen was obtained

“…The choice of these compounds is due to the mechanism of attack of aliphatic hydrocarbons by oxygen atoms and the composition of the resulting products. According to references [13][14], in the system of liquid-phase oxidation, the most subjected to oxygen atoms attack are methylene groups of hydrocarbon. Therefore,…”

The reactions of liquid-phase oxidation of aliphatic oxygen containing hydrocarbons, in particular, nonanol-4 and nonanon-4 in the presence of polyethylene-polyamine complexes (PEPA) with sorbated ions of metals with changeable valency (Co2+,Cu2+, Ni2+) were studied. It revealed that the oxidation of nonanole-4 and nonanone-4 in the presence of Cu2+ and Ni2+ ions in the analyzed system is less active while in the presence of Co2+ ions decarboxylation of acids it is practically absent and it leads mainly to formation of carbonic acids. It has been established that the character of oxidation reaction mostly depends on the properties of metals fixed on polymer matrix.
