Formaldehyde → N-Methyl dicyclohexylamine

Participants

Reaction Steps

In a similar manner to Example 1, 204.0 g (1.13 mol) of dicyclohexylamine and 185.5 g (1.80 mol) of formaldehyde (29.1%) are reacted in a 1 l autoclave; a maximum pressure of 2.4 MPa is established at a temperature of 160° C. After the end of the reaction, 50 g of hexene-1 are added and the organic phase is removed from the aqueous phase. The remaining organic phase is subsequently distilled. 226.3 g of N-methyldicyclohexylamine having a purity of 93.7% are isolated, corresponding to a yield of 96.1% of theory.
