Abstract
3,4-dimethylaniline was prepared by catalytic hydrogenation with Raney nickel catalyst using 3,4-dimethylnitrobenzene as staring substrate.Effects of hydrogenation have been investigated in the optimized conditions: w(catalyst/substrate)=5% in ethanol,initial concentration of the substrate=1.25 mol/L,60 ℃ and 0.8 MPa.Both reactant conversion and the purity of 3,4-dimethylaniline can be up to 100%.
