Abstract
Liquid phase pentanoic acid hydrogenation in nonpolar hydrocarbon solutions (180oC, hydrogen pressure 25 bar) was studied over rhenium on titanium oxide catalysts modified also with group VIII metals - platinum, palladium, ruthenium and rhodium. It was shown that during hydrogenation pentanoic acid was converted into pentanol followed by esterification with unreacted pentanoic acid into its pentyl ester, resulting in an equilibrium mixture of pentanoic acid - pentanol – pentyl pentanoate. Conversion of pentanoic acid increased in the row PdRe/TiO2
