文摘The synthesis of dialkylureas from amines by oxidative carbonylation with sulfuric acid modified zirconia supported palladium catalyst was investigated under relatively mild reaction conditions. High conversions and yields for the synthesis of symmetric dialkylureas from the reaction between same aliphatic amines were achieved. This supported catalyst can also be easily separated and recovered from the solvent after the reaction.
