Abstract: | The hydrogenation of soybean oil methyl esters using aqueous formic acid salts solutions and heterogeneous palladium-on-carbon
catalyst was investigated. Complete hydrogenation of the methyl ester was achieved by mixing a concentrated aqueous alkali
formate solution with the methyl ester at 80 C in the presence of the catalyst (0.2–0.4% Pd). At the initial stages of the
reaction, the selectivity was significantly higher than conventional hydrogenation (hydrogenation under pressure) performed
with the same catalyste.Cis-trans isomerization was similar to the behavior of conventional techniques. |
