Liquid isopropanol is oxidized to gaseous acetone (the boiling point of acetone is 56 °C), leading to a positive volume change of the reaction and thus resulting in a decreased reversible cell potential. Furthermore, the increasing isopropanol and acetone partial pressures on the anode side lead...
Acetone is oxidized in the liquid phase at elevated temperature and at normal or elevated pressure by passing therethrough a stream of oxygen or an oxygen-containing gas in the presence of an oxidation catalyst, the reaction being carried out at between 65 DEG C. and the boiling-point of ...
A solution of (COCl)2 (67 μL, 0.77 mmol) in CH2Cl2 (0.5 mL) was added to the solution of 3-carbamoyl-piperidine-1-carboxylic acid tert-butyl ester (142.0 mmol) and DMSO (78 μL, 1.1 mol) in CH2Cl2 (1.5 mL) at -78 oC. After stirring for 15 min at -78 oC, Et3N (0.23 mL...

The normal boiling point of acetone is 56.2 degrees C and the molar heat of vaporization is 32.0 kJ/mol. At what temperature will acetone boil under a pressure of 50.0 mm of Hg? The standard enthalpy of vaporization (Delta H_vap) of ethanol (CH_3...
while the boiling point is 83oC. This liquid is miscible with water and is stable under normal conditions. Isopropyl alcohol is a colourless, clear, and flammable liquid. Moreover, it oxidizes violently to produce acetone. When considering the applications of this alcohol, it is useful as a ...
However, an evolution in the surface acid–base properties of catalyst is observed. The presence of 0.25% of rhodium produces a decrease of the amphoteric character of the catalyst. The magnitudes of methanol and acetone ∆Gsp decrease from 10.9 kJ/mol and 14.5 kJ/mol, respectively, to 9.3...
