Surface models in heterogeneous catalysis : The synthesis of ammonia and the conversion of carbon monoxide
(Elsevier, 1967-05)
The establishment of chemical equilibria between gas and solid catalysts during the synthesis of NH3 and the conversion of CO is considered. Suitable solid-gas equilibrium reactions are discussed. With the correct choice ...
The low temperature oxidation of ammonia over a supported ruthenium catalyst
(Elsevier, 1967-08)
Kinetics of the nonisothermal pyrolysis of propane
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1967-01)
A method was devised to yield chemical reaction kinetic parameters from nonisothermal, nonisobaric flow experiments. The system studied was the pyrolysis of propane at high temperatures (800° to 1,000°C.). At these ...
Effect of 2-N-mono- and 2-N-diethylaminoethanol on normal and choline-deficient rats
(Elsevier, 1967)
In rats, the acute oral LD50 value of neutralized 2-N-monoethylaminoethanol (MEAE) was found to be 1.0 (0.68-1.35) g/kg. The acute oral toxicity of MEAE, but not that of 2-N-diethylaminoethanol (DEAE) could be largely ...
Stability of a fluid in a rectangular region heated from below
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1967-01)
Finite-difference methods were used to compute hydrodynamic instability due to natural convection in an enclosed horizontal rectangular region heated from below. Critical Rayleigh numbers were determined for a series of ...
A force field for secondary chlorides
(Elsevier, 1967-08)
A force field has been derived for monochloro- and 2,4-dichloro-hydrocarbons. The Snyder-Schachtschneider force field for hydrocarbons was used as a starting point, the constants associated with the secondary chlorine being ...
Protein-carbohydrate interaction : V. Further inhibition studies directed toward defining the stereochemical requirements of the reactive sites of concanavalin A
(Elsevier, 1967-07)
Inhibition studies on the concanavalin A-dextran interaction have been extended using as inhibitors the members of the maltose-, isomaltose-, and methyl [alpha]-isomaltoside series, amino and N-acetyl amino sugars, and a ...
Purification of pyridine for voltammetric studies : Effect of impurities
(Elsevier, 1967)
Purification of pyridine by zone fractional crystallization reduces the concentration of prewave-producing contaminant below polarographic detection limits, i.e., 0.01 mM. A qualitative test based on the stability of the ...
