Abstract:
A method for producing alkoxylated amides of general formula (I) R?1-CO-NR2-CHR3-CHR4-O-(CHR5-CHR6-O)¿n-H, wherein glycerides of the following fatty acids of general formula (II) R1-COOH are made to react with amines of general formula (III) HNR2-R7 to form amides of general formula (IV) R?1-CO-NR2R7¿ and glycerine, and subsequently, the glycerine formed is separated by adding an aqueous acidic solution to form a reaction mixture until a pH value of the mixture ranges from 1 to 7 in order to carry out phase separation in an aqueous phase containing glycerine and an organic phase containing an amide of general formula (IV), the aqueous phase is separated and subsequently, the amid of general formula (IV) is made to react with ethylene oxide and/or propylene oxide and/or butylene oxide to form alkoxylated amides of general formula (I).
