Title:
CONTINUOUS METHOD FOR ACYLATING AMINO GROUP-CARRYING ORGANIC ACIDS
Document Type and Number:
WIPO Patent Application WO/2011/000461
Kind Code:
A3
Abstract:
The invention relates to a continuous method for N-acylating amino group-carrying organic acids by reacting at least one carboxylic acid of formula (I) R1-COOH (I), wherein R1 represents hydrogen or an optionally substituted hydrocarbon group with 1 to 50 carbon atoms, with at least one at least one amino group-carrying organic acid of formula (II) R2NH-A-X (II), wherein A represents an optionally substituted hydrocarbon group with 1 to 50 carbon atoms, X represents an acid group or the metal salt thereof and R2 represents hydrogen, an optionally substituted hydrocarbon group with 1 to 50 C atoms or a group of the formula –A-X, wherein A and X independently are defined as above, 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 amide.
