| 摘要 |
The invention relates to a continuous method for producing amides, according to which at least one carboxylic acid of formula (I) R3-COON (I), wherein R3 is an optionally substituted alkenyl group comprising between 2 and 4 carbon atoms, is reacted with at least one amine of formula (II) HNR1R2 (II), wherein R1 and R2 are independently hydrogen or a hydrocarbon radical comprising between 1 and 100 C atoms, to form an ammonium salt and/or a Michael adduct, and said ammonium salt is then reacted to form a carboxylic acid amide. under microwave irradiation in a reaction pipe, the longitudinal axis of the pipe being oriented in the direction of propagation of the microwaves of a monomode microwave applicator. |
