Steps:

2 Example 2

Equipped with a blender,Thermometer and water separator in a 1000mL three-necked flask was added 444g of di-n-propylamineAnd 64g of 94% paraformaldehyde, with constant stirring, heated to 120 dehydration condensation reaction,The reaction was evaporated to dryness (about 2h), the reaction was completed. About 50g of di-n-propylamine is distilled off excessively under normal pressure,Then vacuum distillation, collecting 100 ~ 110 / 20mmHg) fraction,To obtain bis (di-n-propylamino) methane 402g (theoretical 428g),Yield 93.93%, content 98.9%.
