AB  - Fulvic acids (FAs) from the whole Quaternary sequence (to a depth of 26 m) of the alluvial sediment of the Sava river (taken from a site in Novi Beograd, Belgrade, Yugoslavia) were investigated with the aim of examining the effect of the environment (clay or sand) on their characteristics. Characterization of the FAs was carried out by correlating the results obtained by various instrumental techniques (u.v.-vis. and i.r. spectroscopy, fluorimetry). Differences were noticed between the FAs, depending on whether they originated from sand or clay, which indicates that the hydrogeological environment represents an important factor in determining their characteristics, though the role of the precursor material may be significant. FAs found in clay layers are less aliphatic, have a greater non-aliphatic hydroxyl group content and exhibit more similar fluorescence ntensities compared to FAs originating from sand. The greater mutual similarities of the clay FAs in comparison to those from sands is a result of diagenesis occurring in a more "closed" system.

AB  - An attempt was made to distinguish metal-organic matter interactions in two types of sulfate-reducing environments, mild (MR) and strong sulfate-reducing (SR), in the Aleksinac oil shale deposit (Oligocene-Miocene). Samples from the MR group show (all differences are statistically highly significant): lower organic matter content, compared with the SR group, higher O/C and N/C ratios (0.147 ± 0.054 and 0.041 ± 0.014, respectively, compared with 0.125 ± 0.031 and 0.035 ± 0.008, respectively, in the SR group), and higher Cu, Zn, Pb, Cr, Mo and Co contents than in the SR group. Statistically significant correlations between metals, the N/C and the SiO2/Al2O3 ratio in the MR group only, represent a record of highly interdependent processes of organic-metal-silicate interactions which had been occurring in the mild sulfate-reducing conditions during oil shale formation.

AB  - Oxide formation and oxygen reduction on gold have been investigated with single crystal electrode surfaces of various orientations. Both reactions show sensitivity to the surface orientation, presence of steps, their density and orientation. The initial stages of oxide formation can be correlated with calculated relative surface energy. Anions exert a pronounced effect on oxide formation. The activity for oxygen reduction can be correlated with the same surface property except for Au(100). Structural effect from this particular plane outweighs the electronic effects. No correlation for alkaline solutions was found. Rotating ring-disc measurements show no hydrogen peroxide generation Au(100) in the presence of almost neutral AuOH-(1 - λ)on the surface. This makes it the most active electrocatalyst for oxygen reduction in alkaline solutions. At more negative potentials (no AuOH on the surface) a series mechanism up to the peroxide stage is operative. The Au(311) plane also shows a high activity dependent on AuOH-(1 - λ). Data for both reactions clearly demonstrate that each crystallographic orientation gives an electrode surface with distinct electrochemical properties.

AB  - The adsorption of hydrogen and sulphuric acid anions has been studied on single-crystal platinum stepped surfaces from the [110] zone. Both processes depend on the orientation of the electrode surface. The multiple states of hydrogen adsorption can be correlated with the nature and density of the adsorption sites. There is a negligible effect of adsorbate-adsorbate interaction. The voltammetric profiles are in a wide potential range determined by bisulphate and sulphate adsorption/desorption. A sharp peak found in voltammetry is associated with hydrogen adsorption in the step sites, composed of the (100)-(111) step-terrace combination, concurrent with sulphate desorption. Bisulphates and sulphates are strongly adsorbed in the trigonal sites in the step, which can be formed from the steps and terraces of different orientations from this zone. The exact position of the adsorbed hydrogen atoms and anions is discussed. A comparison with the adsorption in HClO4 is given for some surfaces.

AB  - Ethylene glycol is a potential fuel of practical interest whose electrooxidation has not been studied in detail. This is a complex reaction whose mechanism is far from being understood. It is quite clear, however, that some kind of strongly bound intermediate is formed in the oxidation of ethylene glycol on platinum. This is indicated also by the effects of foreign metal adatoms covering a part of the Pt surface. Thus, pronounced catalytic effects of Pb, Tl and Bi have been observed in alkaline solutions and these are partly based on a suppression of formation and/or adsorption of strongly bound intermediates. In this work the oxidation of ethylene glycol on gold single crystals with the (100), (110) and (111) orientations has been studied with the aim of investigating whether there is structural sensitivity in this reaction. Structural sensitivity, as well as the role of AuOH species formed on surfaces, could be of interest for both electrocatalysis and catalysis.

AB  - In order to obtain evidence on the relationship between kerogen structural types and the quantity and nature of their oxidation products, the products of a multistage (13 step) alkaline permanganate degradation of type-III kerogen from a sample of the Mannville shale, Canada, have been studied in detail. High yield of oxidation products was obtained, 81.89% based on original kerogen: 0.61% neutrals and bases, 4.82% of ether-soluble acids, and 76.46% of precipitated ether-insoluble acids. The ether-soluble acids and the soluble acids produced by further controlled permanganate degradation of precipitated acids were found to consist of different mono- and polycarboxylic, partly alkyl-substituted, aromatic acids as major oxidation products (over 90%). Saturated unbranched mono- and dicarboxylic acids were found in small concentrations. In this way a typical aromatic structure of type-III kerogen was confirmed. The structure of the examined kerogen is probably largely alkyl-substituted and cross-linked by relatively short chains or bridges.

AB  - The products of a 27-step alkaline permanganate degradation of a type II kerogen from a sample of Toarcian shale, Paris Basin, have been studied. The high yield of oxidation products consisted of 1.86% neutrals and bases, 24.48% ether-soluble acids, and 45.95% precipitated, ether-insoluble acids, based on weight of original kerogen. The ether-soluble acids and the soluble products of further permanganate degradation of precipitated acids were found to consist mostly of saturated unbranched C6-C22 α,ω-dicarboxylic and C9-C25 monocarboxylic acids. Significant amounts of aromatic monocarboxylic, dicarboxylic and tricarboxylic acids were also found. Alkane tri- and tetracarboxylic acids were obtained in small concentration.

AB  - Corrosion of pure and amalgamated zinc in pure concentrated KOH solutions was investigated using two methods: (a) galvanostatic measurements of the kinetics of hydrogen evolution with electrodic assessment of corrosion properties of the system, and (b) volumetric measurement of the hydrogen evolution reflecting directly the rate of corrosion. The latter was followed as a function of time during 150 hr. It was found that the corrosion rate varies considerably with time and was suggested that different factors control the initial and the steady-state corrosion. The initial corrosion rate increases with increasing KOH concentration which is indicative of the chemical mechanism of hydrogen evolution. The change of the corrosion rate with time and the steady-state corrosion rate can be explained in terms of formation of an impermeable ZnO film at the surface. In such a case the concentration dependence of the corrosion rate is inverse with time, which explains some results reported in literature. The amalgamated zinc surface gives complex galvanostatic transients which indicate a new phase formation in the process of initiation of hydrogen evolution, which could pertain to some solid potassium-zinc-mercury alloy.

AB  - Unbranched α,ω-diols are mainly converted by means of lead tetra-acetate in refluxing benzene to the corresponding ethers of di-α-tetrahydrofuryl, di-α-tetrahydropyryl and/or α-tetrahydrofuryl-α′-tetrahydropyryl type. Thus, 1,6-hexanediol affords cis-1,4-dioxaperhydropentalene (Ia) in 15·2% yield; 1,7-heptanediol affords 1,6-dioxaspiro[4.4]nonane (II) in 29·2% yield; 1,8-octanediol cyclizes to 1,6-dioxaspiro[4.5]decane (IIIa) in 39·3% yield; 1,9-nonanediol affords a mixture of di-α-tetrahydrofurylmethane (IV, 33·2%), 2-(α-tetrahydrofuryl)α′-tetrahydropyran (IVa, 3·7%) and 1,7-di-oxaspiro[5.5]undecane (IVb, 3·3%); 1,10-decanediol is oxidized to a mixture of 1,2-di-α-tetrahydrofurylethane (V, 27·2%), and threo- and erythro-α-tetrahydrofuryl-α′-tetrahydropyrylmethanes (Va, 4·3%); and 1,11-undecanediol affords, as main product, 1,3-di-α-tetrahydrofurylpropane (VI) in 40·1% yield, together with small amounts of four other ethers which were not identified.

AB  - The lead tetraacetate oxidation of saturated aliphatic alcohols, with structures which do not permit 1,5-cyclization, gave tetrahydropyran derivatives in yields not exceeding 16%. The formation of a small amount of the rearranged ether, 2-ethyl-2-methyltetrahydrofuran, from 4,4-dimethyl-1-pentanol indicates that the cyclization reaction proceeds via an intermediate with carbonium ion character.
