Catalytic transfer hydrogenation of maleic acid with stoichiometric amounts of formic acid in aqueous phase: paving the way for more sustainable succinic acid production

The aqueous phase hydrogenation of maleic acid to succinic acid (SAc) is proved using an efficient and robust Pd/C catalysts and stoichiometric formic acid as source of H 2 . SAc can be separated from the reaction medium by precipitation.
