“…Importantly, H 2 solubility, viscosity and density also did not show any significant correlation with the rates observed, Fig. S13, [61][62][63] nor did the dielectric constant (e) or polarisability (E T (30), E T N ), Fig. S14.…”

a b s t r a c tThe hydrogenation of 4-phenyl-2-butanone over Pt/TiO 2 and Pt/SiO 2 catalysts has been performed in a range of solvents and it has been observed that the solvent impacted on the selectivity of ketone and aromatic ring hydrogenation as well as the overall TOF of the titania catalyst with no solvent effect on selectivity observed using the silica supported catalyst where ring hydrogenation was favored. For the titania catalyst, alkanes were found to favor ring hydrogenation whereas aromatics and alcohols led to carbonyl hydrogenation. A two-site catalyst model is proposed whereby the aromatic ring hydrogenation occurs over the metal sites while carbonyl hydrogenation is thought to occur predominantly at interfacial sites, with oxygen vacancies in the titania support activating the carbonyl. The effect of the solvent on the hydrogenation reaction over the titania catalyst was related to competition for the active sites between solvent and 4-phenyl-2-butanone.

“…A significant number of vapour-liquid equilibrium data is available for binary systems involving the four species (H 2 , O 2 , CO 2 , and CH 3 OH) of our interest [14][15][16][17][18][19][20][21][22][23][24]. Only few data were published for ternary systems including both CO 2 and CH 3 OH, i.e., (CO 2 + CH 3 OH + H 2 ) and (CO 2 + CH 3 OH + O 2 ).…”

“…Hydrogen solubility in the primary alcohols increases with carbon chain length [13] and a similar effect is seen with alkanes [14]. However if we compare the rate of hydrogenation of 4-methylaniline for the primary alcohols, an order of methanol [ octanol & butanol [ ethanol [ propanol is obtained while with 4-tertbutylaniline an order of octanol [ ethanol [ butanol was observed.…”
