反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: In a similar manner to Example 1, 314.4 g (2.0 mol) of diamylamine (technical mixture of 18.3% by weight of diisopentylamine, 61.0% by weight of di-n/i-pentylamine and 19.2% by weight of di-n-pentylamine, remainder: 1.5% by weight) and 330.2 g (3.2 mol) of formaldehyde (29.1%) are reacted in a 1 l autoclave; a maximum pressure of 2.5 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 102° C., the water is removed on a water separator. The remaining organic phase is subsequently distilled. 329.1 g of N-methyldiamylamine having a purity of 91.8% are isolated, corresponding to a yield of 88.3% of theory. is established at a temperature of 120° C After the crude amine (aqueous and organic phase) has been degassed at a maximum temperature of 102° C. the water is removed on a water separator The remaining organic phase is subsequently distilled
