Abstract (en)
[origin: WO2011000459A1] The invention relates to a continuous method for producing amides of aromatic carboxylic acids by reacting at least one carbonic acid ester of formula (I) R3-COOR4, wherein R3 represents an optionally substituted aromatic hydrocarbon group with 5 to 100 carbon atoms and R4 represents a hydrocarbon group with 1 to 30 carbon atoms, with at least one amine of formula (II) HNR1R2, wherein R1 and R2 independently represent hydrogen or a hydrocarbon group with 1 to 100 C atoms, in a reaction tube the longitudinal axis of which extends in the direction of propagation of the microwaves of a monomode microwave applicator, under microwave irradiation to form carboxamide.
