    摘要: N-substituted aldonamides are synthesized by the reaction of alkylamines and aldonolactone. Commercially available sources of aldonolactones (e.g., lactobiono-1,5-lactone) include aldonic acid (e.g., lactobionic acid). The presence of the acid leads to the formation of an ammonium salt impurity. The ammonium salt formation during the synthesis of N-alkyl aldonamides was minimized by the addition of an external acid. External acids and, optionally, emulsifiers were utilized to substantially reduce or eliminate the formation of an ammonium salt and to obtain N-substituted aldonamides of high purity.

    摘要: A process of preparing aldobionamides and N-substituted aldobionamides which includes the steps of recovering a by-product of the process (an ammonium salt of an aldobionic acid) and converting it into at least one starting material. Aldobiono-1,5-lactone is reacted with a primary or secondary amine and the resulting solution containing the by-product of the reaction is passed through an anionic exchange column to obtain the eluate containing the starting amine and some aldobionamide. The eluate may be recycled as part of the starting material mixture. Alternatively, the amine and the aldobionamide may be recovered from the eluate, and the amine alone may be recycled. Aldobionate anion is retained on the column and may be converted into the salt of an aldobionic acid and then into the aldobionic acid.
