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 ...
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 ...
Combined lyotropic and thermotropic phase transitions of deoxycholic acid
(Elsevier, 1980)
Phase transitions of deoxycholic acid have been examined by studying systems which form a clathrate during crystallization. It has been shown that, depending upon the type of solvent molecule present, the deoxycholic acid ...
Kerogen structural studies-oxidations with alkaline permanganate and with ferric chloride
(Elsevier, 1980)
Two oxidizing agents were used for structural studies of the kerogen from Aleksinac shale (Yugoslavia), namely: (1) alkaline potassium permanganate, and (2) acidic ferric chloride. (1) The main goal with alkaline permanganate ...
Optical and electrochemical study of underpotential deposition of bismuth on gold electrode
(Elsevier, 1980)
The underpotential deposition of Bi on Au has been investigated by specular reflectance spectroscopy and linear sweep voltammetry. The spectral dependance of ΔR/R caused by Bi adatoms has been determined and compared with ...
Favorski type rearrangement in the lead tetraacetate oxidation of enamines promoted by boron trifluoride
(Elsevier, 1980)
Favorski type rearrangement has been achieved in the lead tetraacetate oxidation of enamines in the presence of boron trifluoride etherate and alcohol.
