The invention relates to a continuous method for producing amides of aromatic carboxylic acids, according to which at least one aromatic carboxylic acid of formula (I)
Ar—COON (I)
wherein Ar is an optionally substituted aryl radical comprising between 5 and 50 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 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芳香
羧酸酰胺的方法,根据该方法,将式(I)Ar—COON中的至少一种芳香
羧酸(其中Ar是一个可选择取代的含有5至50个原子的芳基基团)与式(II)HNR1R2中的至少一种胺(其中R1和R2独立地是氢或含有1至100个碳原子的烃基团)反应,形成
铵盐,然后将所述
铵盐反应形成
羧酸酰胺,在一个反应管中通过微波辐射,管的纵轴沿着单模微波应用器的微波传播方向定向。
