“…Values of the heat of reaction calculated from some previously published equilibria data on the propan-2-01 dehydrogenation do not agree very well with each other [1][2][3][4][5] or with the measured heat of hydrogenation of acetone; 6 the discrepancies range from 100 to 500 cal mole-1. Moreover, values of the free-energy change of the dehydrogenation reaction calculated from published equilibrium measurements differ by between 100 and 300 cal mole-1.…”

Equilibrium constants Kp for the systems containing propan-2-01 + propan-2-one, butan-2-01 + butan-2-one and pentm-3-01+ pentan-3-one were derived from measurements of the composition of mixtures obtained when the vapours were passed with hydrogen over a catalyst held at a measured temperature. Equations expressing the free-energy, enthalpy and entropy changes for the reactions over a range of temperature have been derived from observations by the use of published heatcapacity data. The results are compared with such published thermodynamic data as exist.Thermodynamic quantities for the ideal gas now recorded and not previously measured include the standard entropies of butan-2-01 (85.69 cal deg-1. mole-1) and pentan-3-01 (91.35 cal deg-1. mole-1) and the standard heat of formation of pentan-3-01 (-75.38 kcal mole-1).

“…Moreover, early work on gold films examined the hydrogenation of acetone to iso-propanol [22], although more recently, supported gold catalysts were reported to be inactive for the same reaction [23]. Favourable results are reported in the hydrogenation of a,b-unsaturated aldehydes to the corresponding unsaturated alcohol: acrolein (2-propenal) [24][25][26] and crotonaldehyde (2-butenal) [15,27,28], as well as the selective hydrogenation of unsaturated ketones in the liquid phase [29,30].…”

“…Early studies showed that supported gold can catalyze various hydrogenation reactions, such as those of linear alkenes [1][2][3], alkynes [3,4], cyclohexene [5,6], and acetone [7]. Then, little attention was paid to the hydrogenation properties of gold, probably because of the very low activity of gold supported on oxides when the metal particles are large.…”
