ABSTRACT:
A process for preparing unsaturated nitrogen containing acids such as acrylamidoglycolic acid utilizes a catalyst free route and low pH conditions. An unsaturated amide such as acrylamide is reacted with an aldehyde acid such as acid in an aqueous environment. The unsaturated nitrogen containing acids are typically produced in solution form and can be utilized as such.
