| 摘要 |
The invention relates to a continuous method for producing amides of aliphatic carboxylic acids by reacting at least one carbonic acid ester of formula (I) R3-COOR4 (I), wherein R3 represents hydrogen or an optionally substituted aliphatic hydrocarbon group with 1 to 100 carbon atoms and R4 represents a hydrocarbon group with 1 to 30 carbon atoms, or wherein R3 and R4 form an optionally substituted ring with 5, 6 or 7 ring members, with at least one amine of formula (II) HNR1R2 (II), 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. |
