A study of the radiation-chemical transformation of n-hexane on the surface of aluminum

IR-Spectroscopy of Radiation- Stimulated Processes of Adsorption, Radiolysis, and Hydrogenation on the Surface of Metals in Contact with Hydrocarbons

“…with peaks of 1320 and 1280 cm −1 are attributed to the plane deformation vibrations ν 1 and ν 2 of two different symmetry classes, and a.b. with maxima of 980 cm −1 -the out-of-plane deformation vibration of 〓CH disubstituted ethylene (trans) [10,26,27]. The formation of π-complexes of olefins is also confirmed by the presence of a.b.…”

“…Metal plates of aluminum (Al) and beryllium (Be) reactor materials having a smooth polished surface with a high reflection coefficient (R = 0.88 + 0.05) in the middle IR region (λ = 2.2-25 μm) were used and investigated [9,10]. As the hydrocarbon adsorbate, the authors selected unsaturated pairs of n-hexane (n-C 6 H 14 ), the purification and adsorption of which are described in detail in [10,11]. The formation of gaseous decomposition products-molecular hydrogen and hydrocarbonswas monitored chromatographically and spectroscopically.…”

“…IR absorption spectra of n-hexane in the stretching vibration region of СН adsorbed on the dehydroxylated aluminum surface at room temperature are presented in Figure 2a (curve 1) [8,10]. As can be seen from the figure, the adsorption of n-hexane on the aluminum surface is accompanied by the formation of a number of absorption bands (a.b.…”

“…The observed absorption bands apparently belong to the stretching vibrations of the CH bonds of the fragments CH 3 , C 2 H 5 , etc. bound by aluminum (aluminum alkyls) [6][7][8]10].…”

“…In fact, there are no data on the radiation-chemical decomposition of hydrocarbons on the surface of metals and the radiation hydrogenation of these surfaces under the influence of gamma radiation. This chapter presents the results of work on IR spectroscopic studies of radiation-stimulated heterogeneous processes of adsorption, radiolysis, and hydrogenation on the surface of metals in contact with hydrocarbons [5][6][7][8][9][10][11][12][13][14][15][16][17].…”
