Formaldehyde → 1-Butanamine, N-butyl-N-methyl-

Participants

Reaction Steps

In a similar manner to Example 1, 258.5 g (2.0 mol) of di-n-butylamine and 330.2 g (3.2 mol) of formaldehyde (29.1%) are reacted in a 1 l autoclave; a maximum pressure of 3.2 MPa is established at a temperature of 120° C. After the crude amine (aqueous and organic phase) has been degassed at a maximum temperature of 80° C., the water is removed on a water separator. The remaining organic phase is subsequently fractionally distilled. 274.6 g of N-methyldi-n-butylamine having a purity of 99.6% are isolated, corresponding to a yield of 95.6% of theory.
