Reaction Conditions:

with hydrogen;dimethyl amine;Cu-Cr catalyst Cu₀₂₀₃ Engelhard at 250; under 7500.75 Torr;Product distribution / selectivity;Gas phase;

Steps:

3
Example 3: In a fixed bed reactor containing 5 g of catalyst (Cu0203 Engelhard) a mixture of N,N-dimethylacetamide, DMA and H₂ is introduced. The mixture with a molar composition of amide/auxiliary amine/H₂ of 1/3/30 is preheated and introduced continuously at the catalyst bed at a rate of 2 g amide/h. The reactor is heated at 25CO and operated at 10 bars. At the outlet, the product containing the desired amine is analysed with GC on-line. The product composition (area%) is displayed in table 3.
