Versuchsvorschrift

One hundred parts of acrylamidoglycolic acid (AGA); 517 parts butanol, 1 part concentrated sulfuric acid and 0.1 part monomethyl ether of hydroquinone were mixed in a flask equipped with a Dean Stark water trap and a stirrer. The mixture was heated until homogeneous. After 5-10 minutes 100 ml of toluene was added and the mixture was brought to reflux and held 5 hours until the theoretical amount of water was collected by azeotrope.
