Selective Hydrogenation of Trans,Trans‐Muconic Acid to Adipic Acid over a Titania‐Supported Rhenium Catalyst

Abstract

Metal oxide-supported rhenium catalysts are highly active and selective for the hydrogenation of trans,trans-muconic acid to adipic acid. High yields to adipic acid are achieved (ca. 88 %) over Re/TiO2 catalyst at 210 °C after 5 h, using methanol as solvent. The selectivity of the rhenium-catalyzed hydrogenation of muconic acid to adipic acid may be further enhanced by using acetone or larger alcohols as solvent in comparison to methanol.
