The invention relates to a continuous method for producing amides, according to which at least one carboxylic acid of formula (I) R
3
-COON (I), wherein R
3
is an optionally substituted alkenyl group comprising between 2 and 4 carbon atoms, is reacted with at least one amine of formula (II) HNR
1
R
2
(II), wherein R
1
and R
2
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.
该发明涉及一种连续生产酰胺的方法,根据该方法,至少一个具有化学式(I)R3-COON(I)的羧酸发生反应,其中R3是一个由2至4个碳原子组成的可选择取代的烯基基团,与至少一个具有化学式(II)HNR1R2(II)的胺发生反应,其中R1和R2独立地是氢或包含1至100个碳原子的烃基团,形成铵盐和/或迈克尔加合物,然后将所述铵盐反应形成羧酸酰胺,在微波辐射下在反应管内进行,管的纵轴朝向单模微波应用器的微波传播方向。
