N-ethyl-N-methylcyclohexanamine

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In a similar manner to Example 1, 190.8 g (1.5 mol) of N-ethylcyclohexylamine and 247.6 g (2.4 mol) of formaldehyde (29.1%) are reacted in a 1 l autoclave; a maximum pressure of 2.6 MPa is established at a temperature of 160° C. After the end of the reaction, 30 g of hexene-1 are added and the organic phase is removed from the aqueous phase. The remaining organic phase is subsequently fractionally distilled. 196.9 g of N-methyl-N-ethylcyclohexylamine having a purity of 98.7% are isolated, corresponding to a yield of 91.8% of theory. is established at a temperature of 160° C are added the organic phase is removed from the aqueous phase The remaining organic phase is subsequently fractionally distilled
