Investigation of active carbon for fuel-cell electrodes
(Elsevier, 1969)
The influence of grain size, mode of catalyst impregnation, and different surface treatments on the electrochemical activity of active carbon for hydrogen fuel-cell electrodes was studied. The experiments were done in a ...
Studies on Chlorate Cell Process: III . Depolarization of Cathodic Hydrogen Evolution in the Bipolar Chlorate Cell Process
(IOP Publishing, 1969)
The cathode process of hydrogen evolution in chlorate cells, including possible depolarization, has not been studied to date. High hydrogen polarization at graphite electrodes delayed the industrial application of bipolar ...
Opening of steroid ring a by means of lead tetraacetate
(Elsevier, 1964)
The lead tetraacetate oxidation of cholestan-1β-ol and cholestan-1α-ol in benzene solution did not afford cyclic ethers but resulted, in major part, in the opening of ring A with formation of 1,10-seco-aldehydes. In addition, ...
Studies on Chlorate Cell Process: V . Theory and Practice of a Modified Technology for Electrolytic Chlorate Production
(IOP Publishing, 1969)
A modified technology for electrolytic chlorate production has been developed.
The cell is considered as a hypochlorite generator and the holding
volume as a reactor for the conversion of available chlorine to chlorate. ...
Lead tetraacetate oxidation of saturated aliphatic alcohols.-III. Unbranched primary and secondary alcohols
(Elsevier, 1965)
The action of lead tetraacetate, in benzene solution, on various unbranched primary and secondary aliphatic alcohols containing 4 to 12 carbon atoms has been investigated and the ratio of carbonyl compounds, cyclic ethers ...
A proposal for use of "Tandel" to obtain optimal temperature of electro-optical devices
(Elsevier, 1966)
A proposal is given for the use of Tandel to obtain the desirable temperature of ferroelectric crystal and optimal working temperature of electro-optical devices as well. The variation of ∈ due to temperature inhomogeneity ...
Study of the reactions of hexanitrocobaltates(III) with amino acids. II. Determination of the configuration of dinitrobis(glycinato)cobaltate(III) ions
(USA : American Chemical Society, 1965)
In a previously published paper1 we have undertaken
a study of the reactions of hexanitrocobaltate(III)
with amino acids. The first reaction we studied was
that of glycine with potassium and sodium hexanitrocobaltate(
III). ...
Lead tetra-acetate oxidation of saturated aliphatic alcohols-V. Factors influencing the formation of cyclic ethers and carbonyl compounds
(Elsevier, 1966)
Factors influencing the relative rates of the homolytic and heterolytic processes in the lead tetra-acetate oxidation of unbranched primary and secondary aliphatic alcohols have been investigated, with a view to determine ...
Reactions with lead tetraacetate. I. Oxidation of saturated aliphatic alcohols. Part 1
(Elsevier, 1963)
It was recently shown that various steroid alcohols could react with lead tetraacetate in non-polar solvents to give tetrahydrofuran and tetrahydropyran derivatives. cyclization occurring when the position of and the ...
The conversion of unbranched primary alkyl and arylalkyl amines to nitriles by means of lead tetraacetate
(Elsevier, 1965)
The only amino compounds oxidized so far with lead tetroacetate were primary aromatic amines, which gave mainly the corresponding azo compounds(1), and some tertiary aryldialkyl amines, which in glacial acetic acid in the ...
