Mass transfer between isobutanol and water in concurrent flow through a packed column
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1961-06)
Local and mean rates of transfer of isobutanol into the water-rich phase and of water into the isobutanol-rich phase were measured in concurrent upward flow through a column packed with glass spheres. The use of a two-component ...
Microdetermination of dihydroxyacetone in biological fluids
(Elsevier, 1961-04)
Dihydroxyacetone is reacted with an excess of 2,4-dinitrophenylhydrazine. The excess reagent is removed by the addition of pyruvic acid and followed by partition between benzene and sodium bicarbonate solution. The benzene ...
The reaction between phosphorus trifluorideborane and ammonia : The synthesis of triamidophosphorus-borane,(NH2)3PBH3
(Elsevier, 1961-04)
The reaction of unstable phosphorus trifluoride-borane and ammonia yields the new, stable compound, (H2N)3PBH3.A formal analogy between BH3 and O is developed, and evidence is presented to indicate that the B---P bond is ...
Solid phase transport of glycerol and sodium chloride in resin
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1961-12)
Diffusivities and equilibrium absorption of sodium chloride and glycerol in cation exchange resin Dowex-50 were determined by making a two-constant fit of experimental data to a diffusion model. The variables studied were: ...
Two-phase concurrent flow in packed beds
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1961-06)
Pressure drop and liquid saturation accompanying two-phase concurrent flow have been studied in a variety of packings and with gas-liquid systems having a wide range of fluid properties. Two basic flow patterns were observed ...
Enzymic reactions in mammalian metabolism of [gamma]-hydroxyglutamic acid
(Elsevier, 1961-08-05)
Studies on phosphodeoxyribomutase
(Elsevier, 1961-09-02)
A phosphodeoxyribomutase has been demonstrated in cell-free extracts of Sarcina lutea. The enzyme could be heated to 55[deg] for at least 2 h and still retain activity. It had a pH optimum around 7.2, and the most highly ...
Heat transfer from acoustically resonating gas flames in a cylindrical burner
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1961-12)
Heat transfer from premixed propane-air flames to the cooled wall of a 5-in. I.D. ramjet type of burner was studied with and without flame-generated, sonic oscillations. Frequency and amplitude measurements revealed that ...
