실험 절차

In a 300 cc capacity round bottom flask equipped with a stirrer were put 50.5 g (0.5 mole) of N-methylolacrylamide and 50 cc of water and, as a polymerization-inhibitor, 500 mg of hydroquinone. On the other hand, 43 g (0.5 mole) of morpholine were gradually added thereto while stirring. Afterwards, the entire contents were stirred for 1 hour at 50° to 60°C. The reaction product was concentrated and then recrystallized from ethyl acetate. m.p.; 91°-92°C. In addition, the resulting product was further distilled under reduced pressure to obtain 34.5 g of fraction of 140°-160°C/0.01 mmHg (45.7%).
