Catalytic Hydrogenation of Benzoic Acid
Hydrogenation of benzoic acid using monoand bimetallic catalyst of Ru, Pd, Co, and Re yielded different products. It was observed that 5% Ru/C was an active catalyst for hydrogenation of both aromatic ring and carboxylic group, while Pd/C catalyst hydrogenated only aromatic ring. Ru-Sn/Al2O3 is a chemoselective catalyst for hydrogenation of –COOH group of benzoic acid.
متن کاملAqueous phase hydrogenation of levulinic acid to 1,4-pentanediol.
For the first time, Mo modified Rh/SiO2 was found to be an effective catalyst for the aqueous phase selective hydrogenation of levulinic acid to 1,4-pentanediol. Over such a catalyst, high levulinic acid conversion (100%) and 1,4-pentanediol yield (70%) can be achieved at low temperature (353 K).
متن کاملHydrogenation of linoleic acid by a rumen spirochete.
Borrelia sp. B(2)5, when grown in a medium containing [1-(14)C] linoleic acid in an atmosphere of CO(2), was found to hydrogenate linoleic acid to trans-11-octadecenoic acid.
متن کاملCatalytic Hydrogenation and Oxidation of Biomass- Derived Levulinic Acid
Levulinic acid (LA), 4-oxo-pentanoic acid, is a new platform chemical with various potential uses. In this paper, catalytic hydrogenation and oxidation of levulinic acid were studied. It was shown from experiments that levulinic acid can be hydrogenated to γ-valerolactone (GVL) over transition metal catalysts and oxidative-decarboxylated to 2-butanone (methyl-ethyl-ketone, MEK) and methyl-vinyl...
متن کاملThe Catalytic Properties of PtSn/Al2O3 for Acetic Acid Hydrogenation
Abstract—Alumina supported platinum and tin catalysts with different loadings of Pt and Sn were prepared and characterized by low temperature N2 adsorption/desorption, H2-temperature programed reduction and CO pulse chemisorption. Pt and Sn below 1% loading were suitable for acetic acid hydrogenation. The best performance over 0.75Pt1Sn/Al2O3 can reach 87.55% conversion of acetic acid and 47.39...
