The Dufour Effect. Iii. Direct Experimental Determination Of The Heat Of Transport Of Carbon Tetrachloride-Cyclohexane Liquid Mixtures, Richard L. Rowley, Frederick H. Horne
The Dufour Effect. Iii. Direct Experimental Determination Of The Heat Of Transport Of Carbon Tetrachloride-Cyclohexane Liquid Mixtures, Richard L. Rowley, Frederick H. Horne
Faculty Publications
The heat of transport of carbon tetrachloride-cyclohexane liquid mixtures has been determined directly by Dufour effect experiments. The technique employs a withdrawable ''liquid gate'' to create a nonturbulent, sharp diffusional interface. The partial differential equations governing the barycentric velocity, composition, and temperature distributions are solved with a Crank-Nicholson implicit numerical scheme. This allows inclusion of the composition and temperature dependence of the thermodynamic and transport parameters. For mean mole fraction of carbon tetrachloride x1 between 0.34 and 0.55 and for mean temperature T between 295.13 and 296.43 degreesK, the best least squares fit of the data for the heat of …

The Dufour Effect. Ii. Experimental Confirmation Of The Onsager Heat-Mass Reciprocal Relation For A Binary Liquid Mixture, Richard L. Rowley, Frederick H. Horne
The Dufour Effect. Ii. Experimental Confirmation Of The Onsager Heat-Mass Reciprocal Relation For A Binary Liquid Mixture, Richard L. Rowley, Frederick H. Horne
Faculty Publications
Although experimental verification of Onsager's reciprocal relations has been achieved in a variety of cases, no quantitative test of the heat-mass reciprocal relation for a binary liquid system has previously been reported. We present in this communication experimental proof of the equality of the mass-heat reciprocal relation for the system carbon tetrachloride - cyclohezane.
Potential-Selective Deposition Of Copper From Chloride Solutions Containing Iron, Ralph E. White, James A. Trainham, John Newman, Thomas W. Chapman
Potential-Selective Deposition Of Copper From Chloride Solutions Containing Iron, Ralph E. White, James A. Trainham, John Newman, Thomas W. Chapman
Faculty Publications
The hydrometallurgy of copper may involve leaching of the metal from its ore with an aqueous solution containing cupric and ferric chloride. The subsequent deposition of copper from such a process stream is modeled here in an idealized electrochemical cell with a rotating-disk electrode. The potential distribution and concentration profiles within the diffusion layer are predicted for given potential differences between the electrode and the solution. The cuprous ion, which is formed by the reduction of the complexed cupric ion at the electrode, is stabilized in the chloride solution and can react either at the electrode or with ferric species …

Electrochemical Reduction Of Molybdate In The Presence Of Zinc Chloride In Molten Lithium Chloride-Potassium Chloride Eutectic, R. Cvetkovic, Branko N. Popov, H. A. Laitinen
Electrochemical Reduction Of Molybdate In The Presence Of Zinc Chloride In Molten Lithium Chloride-Potassium Chloride Eutectic, R. Cvetkovic, Branko N. Popov, H. A. Laitinen
Faculty Publications
Two chronopotentiometric waves were observed for the electrochemical reduction of molybdate in the presence of zinc chloride, with quarter-wave potentials of –1.5V and –1.75V vs. the Pt(II)/Pt reference electrode, respectively. It was observed that an increase in the molybdate concentration causes a decrease of the first transition time indicating a chemical reaction between ZnCl2 (which is reduced at –1.5V) and Li2MoO4 in the melt forming ZnMoO4 which is sparingly dissociated in LiCl-KCl eutectic. The equilibrium constant for the observed reaction was calculated. X-ray powder diffraction patterns of the reduction product of ZnMoO4 have been …

Electrochemical Reduction Of Molybdenum(Vi) Compounds In Molten Lithium Chloride-Potassium Chloride Eutectic, Branko N. Popov, H. A. Laitinen
Faculty Publications
Molybdenum (VI) oxide reacts with molten LiCl-KCl eutectic at 450° to form MoO2CI2, which probably is present as an anion MoO2Cl4=, and pyromolybdate, Mo2O7=. Both of these species are electrochemically reduced to MoO2, which can be reoxidized to MoO2Cl2 by current reversal. A second reduction step, observed whether MoO3 or Mo2O72− is added to the melt, can be attributed to the reduction of MoO4−−, formed as a secondary reaction product in the first …

Electrochemical Reduction Of Chromate In The Presence Of Nickel Chloride In Molten Lithium Chloride-Potassium Chloride Eutectic, Branko N. Popov, H. A. Laitinen
Faculty Publications
Chronopotentiometry of chromate in the presence of NiCl2 in molten LiCl-KCl eutectic reveals a diffusion controlled, three electron reduction step. In the presence of excess NiCl2, chromate is reduced at −0.35V vs. Pt(II)/Pt reference electrode and the electroactive species responsible for the chrono-potentiometric wave is estimated to have a diffusion coefficient of 1.06 · 10−5 cm2 sec−1 at 450°C. The stoichiometry of the reduction product depends mainly on the temperature at which the deposit is formed. At 500°C the deposit approaches the composition LiNi2CrO4. X-ray powder diffraction shows the deposit …
