4synthesis methods
-

Yield:5117-13-5 85.9%

Reaction Conditions:

with sodium hydroxide at 85 - 90;

Steps:

6 Preparation of methacryloylmorpholine

To a 100 mL four-necked flask was added 5.43 g (0.040 mol) of propionylmorpholine, 12.97 g (0.16 mol) of formaldehyde solution,Catalyst NaOH 1.6g (0.040mol), keep the temperature at 85 ~ 90 , the reaction of 15 to 20 hours, the crude methacryloyl morpholine. After completion of the reaction, 30 ml of cyclohexane was added to azeotropically dehydrated, the NaOH was removed by filtration, and finally 0.012 g of p-hydroxyanisole (0.0001 mol) was added and distilled under reduced pressure to give 5.36 g of methacryloylmorpholine in a yield of 85.9 %, Purity 98.4%.
