And the article contained the following:
High catalytic activities (TO = 000 -1) have been achieved by novel water-soluble ruthenium catalysts modified with nitrogen-containing ligands such as the bathophenanthrolinedisulfonic acid disodium salt (BPhDS) in the hydrogenation reaction of the renewable polar platform chem. levulinic acid (LA) which possesses a central relevance in the development of biorefineries of the future in a sustainable way to produce with essentially quant. selectivity of 99.9 mol% γ-valerolactone (GVL) in aqueous media. The apparent activation energy of the Ru/BPhDS catalyst was calculated and amounts a relative low value of 53.3 J/mol when one considers that in the LA hydrogenation reaction this catalyst reduces a less reactive keto group into alc. functionality. A recycling experiment of the Ru/BPhDS catalyst by extraction after addition of di-Et ether has shown that the catalyst is stable without loss of activity and selectivity in a consecutive run. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Product Details of 636-73-7
