Direct solution analysis using an arc source incorporating two plasmas rotating in a graphite tube
(Elsevier, 1977)
As a continuation of earlier work on arc sources for the spectrochemical analysis of powdered samples, a source appropriate for multi-element analysis of trace elements in solution has been developed. The nebulized solution ...
Acetoxylation of steroidal lactones by means of lead tetraacetate
(Elsevier, 1970)
One of the structural features of many bitter principles ls the presence of a &-lactone ring. Some of these compounds differ from one another by the state of oxidation of the molecule as a whole and also by the state of ...
Remote functionalisation by ferrous ion-cupric ion induced decomposition of alkyl hydroperoxides
(Pergamon Press, 1979)
By decomposition of alkyl hydroperoxides 1-8 with ferrous sulfate-cupric acetate reagent, intramolecular functionalisation of remote non-activated C atom takes place and unsaturated alcohols with double bond mainly at ...
Hydrogen evolution on platinum in the presence of lead, cadmium and thallium adatoms
(Pergamon Press, 1979)
Hydrogen evolution on rotating platinum electrode has been measured in the presence of Pb, Tl and Cd adatoms. At low coverages of these adatoms (θM < 0.5) the mechanism of H2 evolution is the same as that for Pt, giving ...
Investigation of occluded and nonoccluded synthetic zeolites. Base-catalyzed demethylation of tetramethylthionine-methylene blue on a denitrated zeolite
(Elsevier, 1972)
The adsorption of methylene blue from aqueous and non-aqueous media onto the zeolite NaA, the occluded zeolite NaANaNO3 and the denitrated zeolite NaANa2O has been investigated. Adsorption isotherms have a standard form ...
A novel procedure for the aromatization of ring a in 19-nortestosterone
(Elsevier, 1977)
A convenient, 40% overall yield synthesis of 2,3,17β-triacetoxy-1,3,5(10)-estratriene is described, which involves epoxidation of 19-nortestosterone and subsequent acetylation, lead tetra-acetate acetoxylation of the ...
Effect of codeposition of polymer on the morphology of electrodeposited copper
(Kluwer Academic Publishers, 1979)
Poly(4-vinyl pyridine-co-methyl methacrylate), which is soluble in water in its protonated form and insoluble as a neutral molecule, has been synthesized and introduced into an acid bath for copper deposition. Potential-sweep ...
The effect of the plasma composition on characteristics of the d.c. arc-II. Arc in argon and arc in nitrogen with water vapour
(Elsevier, 1971)
The experimental and theoretical curves of the radial temperature distribution of the arc burning in argon, are compared with the corresponding curves in nitrogen. The theoretical curves are obtained by solving the ...
The effect of the plasma composition on characteristics of the d.c. arc-III. Arc in carbon dioxide
(Elsevier, 1971)
The experimental and theoretical curves of radial temperature distribution of the arc burning in carbon dioxide, compared with corresponding curves in nitrogen, are considered. The theoretical curves are obtained by solving ...
A new technique for measuring adsorption on non-noble metals
(Elsevier, 1974)
A new technique for measuring adsorption on non-noble metals is presented here on the basis of former experimental results and experience.
