Abstract: The effects of the preparation conditions of Pd/C catalyst and the promoters on the catalytic property have been investigated. The influences of partial oxygen pressure and addition of nitrobenzene on the oxidative carbonylation of aniline to ethyl N-phenyl carbamate also have been tested. The Pd/C catalyst was characterized by XPS, TPR and in situ IR techniques. A possible mechanism of the oxidative carbonylation of aniline catalyzed by Pd/C NaI system in alcohol medium has been proposed.

Key words: aniline, oxidative carbonylation, ethyl N-phenyl carbamate, palladium
