Selective Reduction of Chloronitrobenzene to Chloroaniline on Ni/Al2O3 Catalysts Got-up Ionic Liquids

Ionic liquids-modified Ni/Al2O3 catalysts are found to be alternatively excellent media for the heterogeneously catalyzed hydrogenation of halonitrobenzenes to corresponding haloanilines.It gives rise to higher selectivity and lower dehalogenation in the hydrogenating process compared with that observed in conventional nickel catalyst.
