Catalytic performance of rare earth oxides in ketonization of acetic acid
TL;DR: In this article, a series of rare earth oxides were investigated as catalysts in the ketonization of acetic acid, and high selectivity to acetone over 99% was obtained by reacting acetic acids over rare earth Oxides such as La 2 O 3, CeO 2, Pr 6 O 11, and Nd 2 O3.

Transformation of bio-derived acids into fuel-like alkanes via ketonic decarboxylation and hydrodeoxygenation: Design of multifunctional catalyst, kinetic and mechanistic aspects
TL;DR: In this paper, a review illustrates the development of different approaches to one-pot synthesis of fuel-like alkanes from lignocellulose derived carboxylic acids where particular focus is given to valeric acid consecutive decarboxylative coupling and ketone hydrodeoxygenation in a single reactor over one catalyst bed.

Studies on the ketonization of acetic acid on chromia: II. The surface reaction
R. Swaminathan,J.C. Kuriacose +1 more
TL;DR: In this paper, a mechanism for the surface reaction of acetic acid on chromia is suggested and discussed based on a comparison of the energies of activation and the previously established fact that both the dehydration and dehydrogenation activity of chromia are required for the ketonization reaction.

Modification of the activity of chromia and chromia-alumina catalysts by adsorbates
TL;DR: In this paper, the effect of doping semiconductor oxides can be simulated by mixing reactants with other substances, such as acetic acid or hydrogen, in the light of the effect the chemisorption of various compounds has on the electronic character of the catalyst.
