摘要

A novel egg-shell Pd–S catalyst with palladium metal as the core and a membrane of palladium sulfide as the surface has been prepared by sulphidizing Pd/C with H2S. This catalyst is effective for the reductive alkylation of p-amino diphenylamine (PADPA) and methylisobutyl ketone (MIBK) to afford N-(1, 3-dimethylbutyl)-N′-phenyl-p- phenylenedianine (DBPPD) with conversion up to 99.42% and selectivity to 97.46%. ...
