Keywords:
Poly-4(vinylpyridine) and Mn based catalysts, oxidation of n-alkanes
,
n-heptane
Polymer based catalyst has been studied for the oxidation of n-alkanes
in
the mild condition, 40-110
0
C and atmospheric pressure.
Quaternized crosslinked manganese-containing polymeric (based on
poly-4- vinylpyridine (P4VP) and N, N/methylene-bis-acrylamide (MBAA))
catalytic systems examined on the oxidation of n-heptane to obtain heptanol
1; 2; 3; 4, heptanal and heptanone were synthesized and characterized. It
has been established that manganese-containing complexes formed in the
catalytic reaction are responsible for the oxidation of n-heptane by oxygen
(Fig. 1). As can be seen from Figure 1, the conversion of the initial product
increases when temperature is rising which is associated with the formation
of by-products, but this leads to decreasing in the yields of the target products
(alcohols).
The structure and phase composition of the prepared catalysts was
determined by X-ray diffraction analysis (XRD; D2-Phaser Bruker
diffractometer), FT-IR spectroscopic analysis (FT-IR spectroscopy Nicolefisio
VSA), scanning electron microscopy (SEM and EDS on Sigma VP. Carl Zeiss
Jena), The products of the catalytic testing were
analyzed using a Agilent
Fig. 1.
