Yield:868-77-9 97.18% ，97-90-5 2.82%
Reaction Conditions:
with 10H-phenothiazine;toluene-4-sulfonic acid at 100; for 2.5 h;Temperature;Time;
Steps:
1-21; 23; 25; 26-34 Examples 6-10
Measure 30 mL of MMA (28.2 g) into a 250 mL three-necked flask.And weighed 0.25 g of the inhibitor phenothiazine into a three-necked flask.After the dissolution of the polymerization inhibitor was completed, 23.6 mL (18.6 g) of ethylene glycol was added.And weighed 1.72g of p-toluenesulfonic acid into a three-necked flask and reacted in an oil bath for 2.5 hours.The reaction temperatures are 100 ° C, 105 ° C, 110 ° C, 115 ° C, 120 ° C,After the reaction,Cool to 50 ° C,Distilled under reduced pressure to remove low boilers,Collecting the main product 86-88 ° C / 0.67 kPa main product hydroxyethyl methacrylate and98-100 ° C / 0.67 kPa by-product ethylene glycol dimethacrylate,Calculate the yield and the primary to secondary ratio.
