  • Publication number: 20240317674
    Abstract: A process for catalytic hydrogenation of aromatic amines can be performed. The aromatic amines can be methylenedianiline and/or tolylenediamine. The ring-hydrogenated equivalents can be obtained by contacting an input product, which have the aromatic amines and impurities, such as, alcohols, glycols, polyols, organic acids and/or water, with hydrogen in the presence of a catalyst. The catalyst can be platinum, palladium, rhodium, ruthenium, nickel, cobalt and/or iron. The catalyst is applied to a support, wherein the input product that has aromatic amines result from a PU decomposition process and contains impurities from this decomposition process.
