Lewis acid-base titrations employing megacycle-frequency oscillators : Part III. Preparation, isolation and characterization of some adducts predicted from titration curves
(Elsevier, 1963)
Adducts of stannic chloride with thirteen oxygen bases, isolated as solids from benzene or heptane solution, were characterized by analysis and melting point behavior; several of these are new compounds. Diethyl ether, ...
The distribution of reaction rates and activation energies on catalytic surfaces: Exchange reaction between gaseous benzene and benzene adsorbed on platinum
(Elsevier, 1963-10)
A mathematical derivation for the calculation of the distribution function of rate constants and activation energies for an isotopic exchange reaction between chemical species adsorbed on a solid surface and in the surrounding ...
Lewis acid-base titrations employing megacycle-frequency oscillators : Titration involving stannic chloride in acetonitrile and benzene solution
(Elsevier, 1963)
By using a megacycle-frequency oscillator to follow the reaction, the Lewis acid, stannic chloride, can be titrated with nitrogen bases in acetonitrile as solvent and with oxygen bases in benzene as solvent with an error ...
The hydrogen-deuterium exchange reaction on cobalt ferrite
(Elsevier, 1963-08)
The catalytic activity of cobalt ferrite, Co3-xFexO4, for the hydrogen-deuterium exchange reaction and the change in thermoelectric power of the ferrite during the adsorption of hydrogen and oxygen were investigated as ...
Immunochemical studies with citrate-condensing enzyme
(Elsevier, 1963)
Anti-enzyme to citrate-condensing enzyme from pig heart was prepared in rabbits. The interaction of the enzyme and anti-enzyme was not dependent on pH between 6.3 and 8.9 nor was it dependent on temperature at 0[deg] or ...
The participation of pyridoxal phosphate, carnosine and calcium in the reversal of contraction in muscle fiber systems
(Elsevier, 1963-01)
A relaxing system requiring phosphocreatine as the relaxant may be restored to glycerinated psoas fibers by incubation in a reaction mixture containing pyridoxal phosphate, calcium, carnosine, magnesium, ATP, and sodium ...
Studies on the estimation of deoxyribonucleic acid and ribonucleic acid in rat brain
(Elsevier, 1963)
A method for the estimation of DNA and RNA in rat brain is described. The principal modifications of preexisting methods involve initial lipid extraction with chloroform-methanol and continuous stirring during alkaline ...
