Reaction Conditions:
with 10H-phenothiazine in toluene at 155;Temperature;
Steps:
8
Will be 120.53g methacrylic acid,134.17 g of diethylene glycol diethyl ether, 12.73 g of catalyst S2O82-/ZrO2-SiO2, 38.20 g of toluene, 1.27 g of phenothiazine was added to the four-necked flask, the degree of vacuum is -0.04 to -0.045 MPa, and the temperature is raised to reflux after heating, and the temperature is continuously raised to 155 ° C. Timely separate the water from the water separator, the molar ratio of the reaction raw materials is methacrylic acid:diethylene glycol ether = 1.4:1; the amount of the catalyst is 5% of the total mass of the raw materials; the amount of water-carrying agent is 15% of the total mass of the raw materials; the amount of the polymerization inhibitor is 5% of the total mass of the raw materials. The molar ratio of the reaction raw materials described therein is methacrylic acid: diethylene glycol diethyl ether = 1.4:1. The conversion of diethylene glycol ether was 98.71%, the yield of diethylene glycol diethyl ether methacrylate was 92.49%.
