Reaction Conditions:
with dinoseb in ethanol;isopropyl alcohol at 30 - 40; for 3 h;Temperature;Time;
Steps:
3 Example 3
500 ml of a mixed solvent of ethanol and isopropyl alcohol was added to a 1000 ml four-necked flask equipped with a mechanical stirring and a thermometer, and 250 ml of ethanol and isopropyl alcohol were mixed in the solvent, and 160 g of dimethylamino methacrylate was added to the flask.The polymerization inhibitor o-sec-butyl-4,6-dinitrophenol 0.2g was stirred and dissolved until it was uniformly mixed into a four-necked flask for continuous air protection.Then, 125 g of 1,3-propane sultone was added dropwise to the mixture.The dropping temperature is controlled between 30 and 40 ° C. After the dropwise addition, the mixture is kept at this temperature for 3 hours. After the temperature is completed, the temperature of the mixture is lowered to 10 ° C and filtered, and the solid obtained by filtration is dried. The finished product is obtained and the filtrate recovery sleeve is used in the next batch.Using the method of this example, 273 g of a white solid was obtained.The content of the detected product was 98.88%, the melting point was 150-153 ° C, and the product yield was 95.79%.
