Transfer-hydrogenation process

Page/Page column 15; 16, (2018/06/19)
A transfer-hydrogenation process for preparing a carbonyl compound and an alcohol compound comprises the steps of (a) contacting a first carbonyl compound with a first alcohol compound in the presence of a transfer-hydrogenation catalyst in a first reaction zone at conditions effective to form a second carbonyl compound from the first alcohol compound and a second alcohol compound from the first carbonyl compound, and (b) removing the second carbonyl compound from the first reaction zone during step (a). The first carbonyl compound is a saturated aldehyde or ketone, or an α,β-unsaturated aldehyde or ketone. The first alcohol compound is a primary or secondary alcohol. The second alcohol compound is α,β-saturated. The transfer-hydrogenation catalyst includes a Group 8 to 11 metal. This process is useful for preparing and higher value alcohols, such as butanol or 2-ethylhexanol, from the corresponding carbonyl compounds by engaging lower alcohol (C2-C4) feedstocks instead of hydrogen (H2).

The full composition of the products and the kinetics of their accumulation was studied during the oxidation of a series of unsaturated aldehydes by peroxy acids.The effects of the temperature, the structure of the aldehyde, and the solvent on the reaction rate and quantitative composition of the products were determined.A kinetic model of the reaction is proposed, and its parameters are calculated.New data are obtained on the mechanism of the Baeyer-Villiger reaction as applied to the oxidation of unsaturated aldehydes by peroxy acids.
