catalytic 1 Propanol oxidation on size controlled platinum nanoparticles at solid gas and solid liquid interfaces significant differences in kinetics and mechanisms
Journal of Physical Chemistry C, 2019Co-Authors: Fudong Liu, Huiling Han, Lindsay M Carl, Danylo Zherebetskyy, Linwang Wang, Gabor A SomorjaiAbstract:Utilizing Pt nanoparticles of varying sizes (2–7 nm), it was found that the oxidation of 1-Propanol by molecular oxygen at 60 °C to propanal at the solid–gas and solid–liquid interfaces yielded significantly different results depending on Pt particle size and alcohol surface density. The reaction rate at the solid–gas interface was found to be 1 order of magnitude greater than that at the solid–liquid interface after normalizing concentration. In addition, catalytic activity increases with the size of Pt nanoparticles for both reactions. Moreover, water substantially promoted 1-Propanol oxidation in the liquid phase, yet it inhibited the reaction in the gas phase. The gas phase and liquid phase reactions are believed to undergo different mechanisms due to differing kinetic results. This correlated well with different orientations of the 1-Propanol species at the solid–gas interface versus the solid–liquid interface as probed by sum–frequency generation vibrational spectroscopy (SFGVS) under reaction condi...

Equilibrium diagram of the water + K2SO4 or Na2SO4 + 1-Propanol or 2-Propanol systems at boiling conditions and 101.3 kPa
Fluid Phase Equilibria, 2020Co-Authors: Alejandro Gomis, Jorge Garcia-cano, Juan Carlos Asensi, Alicia Font, Vicente GomisAbstract:Abstract Thermodynamically consistent phase equilibrium data at 101.3 kPa and boiling conditions were determined for the ternary systems water + Na2SO4 + 1-Propanol, water + Na2SO4 + 2-Propanol, water + K2SO4 + 1-Propanol and water + K2SO4 + 2-Propanol. In contrast to the systems with Na2SO4, the salting-out effect of K2SO4 was not sufficient to split the miscible Propanol + water mixture into two liquid phases. The UNIQUAC equation extended to electrolytes for the liquid phase activity coefficients was used to predict the phase equilibria of all the systems. The model reproduced the experimental results quite well, except for the ternary system water + K2SO4 + 1-Propanol. In this case the model predicted liquid-liquid splitting into two liquid phases, when there is not.

Liquid-liquid-solid equilibria for the ternary systems water-lithium chloride-1-Propanol or 2-Propanol at 25 °C
Fluid Phase Equilibria, 1996Co-Authors: Vicente Gomis, Francisco Ruiz, Juan Carlos Asensi, Pilar CayuelaAbstract:Liquid-liquid-solid equilibria for the ternary systems water-lithium chloride-1-Propanol and water-lithium chloride-2-Propanol at 25 °C have been measured experimentally. The equilibrium diagrams determined show differences between the two systems. In the system with 1-Propanol, the solid phase of the liquid-liquid-solid region is monohydrated salt. However in the system with 2-Propanol it is anhydrous salt.

Liquid-liquid-solid equilibria for the ternary systems water-sodium chloride or potassium chloride-1-Propanol or 2-Propanol
Fluid Phase Equilibria, 1994Co-Authors: Vicente Gomis, Francisco Ruiz, Guillermo De Vera, Eladio López, M. Dolores SaqueteAbstract:Abstract Gomis V., Ruiz F., De Vera G., Lopez E. and Saquete M.D., 1994. Liquid-liquid-solid equilibria for the ternary systems water-sodium chloride or potassium chloride-1-Propanol or 2-Propanol. Fluid Phase Equilibria, 98:141-147. Liquid-liquid-solid equilibria for the ternary systems water-sodium chloride-1-Propanol, water-potassium chloride-1-Propanol, water-sodium chloride-2-Propanol and water-potassium chloride-2-Propanol have been measured at 25°C. The salt effect on the water miscible organic compound is greater with NaCl than with KC1, and greater on the 1-Propanol than on the 2-Propanol.
