Continuous flow carbamoylation of aniline by dimethyl carbonate using a microreactor coated with a thin film of ceria supported gold nanoparticles

Selective carbamoylation of aniline by dimethyl carbonate has been performed under continuous flow using a microreactor having 10 μm microchannels and 4 ml of total volume. Nanoparticulated ceria and gold nanoparticles supported on nanoparticulated ceria that have proved to be highly selective in ba...

Summary:Selective carbamoylation of aniline by dimethyl carbonate has been performed under continuous flow using a microreactor having 10 μm microchannels and 4 ml of total volume. Nanoparticulated ceria and gold nanoparticles supported on nanoparticulated ceria that have proved to be highly selective in batch reactions were tested as catalysts. The catalyst coating was deposited as thin film on the stainless steel microreactor plate that was previously activated by heating at 700 °C for 2 h. It was observed that at 120 °C and 5 bar pressure, both catalysts were stable over long times on stream reaching maximum conversions about 35%.
