PROCESS FOR MAKING AN ACRYLAMIDE CONTAINING A DIALKYL ACETAL GROUP

摘要

PATENT 182PUS04072 A process is provided for making an N-substituted acrylamide dialkyl acetal, such as acrylamidobutyraldehyde dimethylacetal (ABDA), by blocking the double bond in an acrylic acid ester with a nucleophile, such as methanol, removing excess nucleophile from the blocked ester, aminating the blocked ester with an amino dialkyl acetal in the presence of an aminolysis catalyst but in the absence of any protic solvent, and deblocking the double bond in the product by pyrolysis.
