Reaction Conditions:

with hydrogen;dimethyl amine;CuCr catalyst Leuna 1970T at 250; under 7500.75 Torr;Product distribution / selectivity;Gas phase;

Steps:

1

Example 1: In a fixed bed reactor containing 15 g of CuCr catalyst (Leuna 1970T) a mixture of N,N-dimethyldecylamide, DMA and H₂ is introduced. The mixture with a molar composition of amide/auxiliary amine/H₂ of 1/3/120 is preheated and introduced continuously at the catalyst bed at a rate of 15 g amide/h. The reactor is heated at 250⁰C and operated at 10 bars. At the outlet, the product containing the amine is separated from the gas by condensation. The liquid outlet is analysed using gaschromatography, the composition (area%) is displayed in table 1. By a simple methylation reaction, N-methyldecylamine can be converted to N,N-dimethyldecylamine reducing the side products to less than 1 %.
