An analysis of elementary processes of water desorption from zeolites of type aPart. I. Zeolites with monovalent counterions: undefined
(Elsevier, 1976)
Complex DSC curves of water desorption from LiA, NaA and KA zeolites were resolved into the most probable elementary curves. The activation energies and transition temperatures of corresponding elementary processes were ...
The polarographic and chronopotentiometric investigation of the copper(II)-ethylenedithioldiacetic acid system
(Elsevier, 1975)
The electrode process of the Cu(II)-ethylenedithioldiacetic acid chelatereduction occurs in two one-electron reduction steps. The reversibility of the first polarographic wave was confirmed by microcoulometry at constant ...
Intramolecular cyclization of 3β-acetoxy-16-picolinylidene-5-androsten-17-one by catalytic hydrogenation
(Elsevier, 1970)
Intramolecular cyclization by catalytic hydrogenation of 3β-acetoxy-16-picolinylidene-5-androsten-17-one (IV) (80° and 50-60 atm of hydrogen pressure over Pd/C as catalyst) gives rise to the formation of two cyclic products, ...
The Reduction of Some 1, 2‐Epoxides with Lithium Aluminium Hydride. Preliminary Communication
(Wiley - VCH Verlag GmbH & Co, 1976)
The factors influencing the ease of the lithium aluminium hydride reduction of various 1,2‐epoxycycloalkanes and 1,2‐epoxyalkanes are described and discussed.
Carbon-air electrode with regenerative short time overload capacity: Part 1. Effect of manganese dioxide
(Springer Nature, 1973)
To increase the overload capacity of the carbon-air electrode in alkaline electrolyte, without seriously changing the electrode potential during short-time overload periods, small amounts of MnO2 were added to carbon and ...
Extractives of Artemisia scoparia
(Elsevier, 1973)
Artemisia scoparia collected south of Belgrade was used. Capillin, 1-phenyl-2,4-hexa-diyne-1-ol, vanillin, and scoparone were isolated. All compounds were identified by direct comparison with authentic materials, by m.m.p., ...
Corrosion of Pure and Amalgamated Zinc in Concentrated Alkali Hydroxide Solutions
(IOP Publishing, 1974)
Corrosion of pure and amalgamated zinc in pure concentrated KOH solutions was investigated using two methods: (a) galvanostatic measurements of the kinetics of hydrogen evolution with electrodic assessment of corrosion ...
Catalytic effects of monolayers of metals deposited at underpotentials: Oxidation of formic acid on platinum
(Elsevier, 1975)
It was recently shown that the monolayers of some metals deposited at underpotentials
on gold can substantially increase the rates of some redox reactions 1 , and the
rate of oxygen reduction:. This note reports the ...
Molybdenum and hydroxybenzene complexes in concentrated sulphuric acid
(Elsevier, 1976)
It is already known [1--5] that Ti, W, V, Mo and some other metals form
coloured complexes with 1,4-benzenediol in concentrated sulphuric acid. We
have also found that hydroxybenzene has similar properties. Papers found ...
Inhibitory effects of manganeous, cadmium and zinc ions on hydrogen evolution reaction and corrosion of iron in sulphuric acid solutions
(Pergamon Press, 1978)
The presence of metal ions (Cd2+, Mn2+, Zn2+), more electronegative than the cathodic potential for the hydrogen evolution reaction on iron in a 0.25M H2SO4 solution, inhibits the hydrogen evolution reaction and corrosion ...
