| titleOfInvention | Method for synthesizing 2-bromine-2-methyl propanal |
| abstract | The invention discloses a method for synthesizing 2-bromine-2-methyl propanal. The method comprises the following steps of: mixing methanol and 2-hydroxyl propanal, and dissolving with stirring at room temperature; slowly dripping bromine into the mixture; reacting with stirring at room temperature for 2 to 4 hours; evaporating under reduced pressure to remove the methanol and the bromine; washing, drying, concentrating until the filtrate is dried, and thus obtaining a 2-bromine propanal crude product for later use; adding the spare 2-bromine propanal crude product obtained in the step 1 into acetonitrile; adding methyl iodide, and reacting with stirring at room temperature for 4 to 6 hours; pouring a reactant into an ice water mixture, and stirring for 0.5 to 1 hour; extracting, drying, and concentrating until the filtrate is dried; adding ethanol, and heating and refluxing for dissolved clarification; and cooling to the temperature of between 0 and 5 DEG C, crystallizing for 5 to 6 hours, filtering, and thus obtaining the 2-bromine-2-methyl propanal. In the method for synthesizing the 2-bromine-2-methyl propanal, used raw materials are readily available; and the method is high in yield, makes operation easy and makes industrial production easily realized. |
