Configuration and reactivity of ten-membered 5,10-seco-compounds obtained by fragmentation of 5-hydroxy-steroids
(Elsevier, 1966)
Assignment of configuration to the 1,10-double bond in the cis-trans isomeric 3β-acetoxy-5,10-seco-1,10-cholesten-5-ones has been achieved by means of NMR spectrometry. Some reactions of these new compounds have been studied ...
Preparation and photolysis of 2-diazo-6-oximino- and 2,6-bisdiazo-4-tert. Butylcyclohexanone
(Elsevier, 1967)
Reaction mechanism of diazoketone photolysie is assumed
to involve the formation ofd-keto-carbene intermediates, final products being dependent on the molecular structure and
reaction medium. Numerous example8 of ...
Studies on Chlorate Cell Process IV. Effect of Neutral Salts on Conversion of Available Chlorine to Chlorate
(IOP Publishing, 1969)
It has been shown that neutral salts, such as Nacl and and Naclo3 and their mixtures, cause an apparent increase in the thermodynamic dissociation constants of weak acids and bases. The pH value of aqueous salt solutions ...
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 ...
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 ...
The reaction of lead tetra-acetate with some unbranched α,ω-diols
(Elsevier, 1969)
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, ...
New Methods of Obtaining Fuel Cell Electrodes: IV . Powder Electrode Fuel Cell with Lateral Feeding
(USA : American Chemical Society, 1969)
A previously developed powder electrode in combination with lateral feeding with gases has been further improved. A fuel cell without gas chambers and with loose carbon powder electrodes has been constructed and tested ...
The structure of glycerol acetals
(Elsevier, 1967)
It is known that the condensation of with polyols yields cyclic acetals. Thus, carbonyl compounds it is known that by condensation of benzaldehyde with glycerol, a mixture of 2-phenyl-5-hydroxy-1,3-dioxane and 2-phenyl-4 ...
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. ...
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 ...
