実験手順

In a similar manner to Example 1, 197.3 g (1.0 mol) of dibenzylamine and 165.1 g (1.6 mol) of formaldehyde (29.1%) are reacted in a 1 l autoclave; a maximum pressure of 1.8 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 distilled. 191.8 g of N-methyldibenzylamine having a purity of 93.8% are isolated, corresponding to a yield of 85.1% of theory.
