Correlative geochemical study of crude oils from southeastern and southern parts of the Pannonian Basin
(Organic Geochemistry, 1988)
Several crude oils from the southeastern Yugoslav part of the Pannonian Basin are correlated for the first time on the basis of many bulk and specific parameters. The investigations involved 15 oils from oil-gas fields A ...
Mass spectrometric analysis of the carbon content in the plasma of a horizontal electric arc burning in a graphite tube / Massenspektrometrische Analyse des Kohlenstoffgehaltes im Plasma einer horizontalen Bogenentladung in einem Graphitrohr
(Springer Science and Business Media LLC, 1981)
The carbon content in the plasma of a horizontal electric arc in a graphite tube, burning in air, in the presence of an inhomogeneous magnetic field has been determined. The modifications with one and two rotating arc ...
Treatment of electrostatic effects within the molecular mechanics Method. 2
(American Chemical Society, 1983)
The previously developed general method, which includes induction by dipoles in polarizable bonds and the solvation of molecular dipoles and quadrupoles, was used to calculate molecular dipole moments and to predict ...
Multistage alkaline permanganate degradation of a type II kerogen
(Elsevier, 1984)
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, ...
Mass-spectrometric analysis of the products formed in a D.C. Arc Plasma / Massenspektrometrische Analyse der im Gleichstrombogen-Plasma gebildeten Produkte
(Springer Nature, 1980)
The carbon content was determined in the plasma of horizontal electric arc discharging between carbon electrodes in a) a graphite tube and b) a ceramic tube, in the presence of an inhomogeneous magnetic field. After 20 s ...
Multistage alkaline permanganate degradation of a type-III kerogen
(Elsevier, 1985)
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 ...
Deuterium‐induced 13C nuclear magnetic resonance isotope shifts and 13C-2H couplings for signal assignments and determination of deuteration site in cyclooctanone
(Wiley, 1981)
Unambiguous signal assignments in the 13C spectra of monodeuterated cyclooctanones derived from the lead tetraacetate or silver oxide/bromine oxidations of the corresponding 1‐monodeutero‐alcohols have been obtained from ...
Circular dichroism of some cyclopropane ring containing 1,3-cyclo-5,10-seco-steroidal ketones
(Elsevier, 1982)
Circular dichroism of the rearranged keto steroids 3 and 4, containing a condensed three and nine-membered ring system, shows that the conformation of the nine-membered ring is the same in solution as in the crystal; ...
Free-radical oxidative transformations of androst-4-ene-3β,9α,17β-triol 3,17-diacetate
(Tetrahedron, 1988)
The oxidation of androst-4-ene-3β,9α,17β-triol 3,17-diacetate (2) with lead tetraacetate resulted mainly In β-fragmentation of the C(9)-C(10) bond to give a mixture of 10α- and 10β-acetoxy-Δ4-unsaturated 9,10-seco-steroidal ...
Synthesis, structure, and reactions of secosteroids containing a medium-sized ring. Part 17. Structure-reactivity relationship in the solvolysis of 5,10-secosteroidal 3-tosylates
(Royal Society of Chemistry, 1980)
Kinetic measurements of the solvolysis of (Z)-3α- and (Z)-3β-, and (E)-3α- and (E)-3β-tosyloxy-5,10-secocholest-1(10)-en-5-ones in buffered aqueous acetone (90 : 10 v/v) reveal that the (Z)-3α-, (E)-3α-, and (E)-3β-tosylates ...
