| titleOfInvention | Method of preparing sodium formyl acetone and 4,4-dimethoxy-2-butanone |
| abstract | The present invention provides a method of preparing sodium formyl acetone using acetone, methyl formate and sodium methoxide as raw materials. A mixture consisting of an acetone and a methyl formate is supplied to a methanol solution of sodium methoxide, or an acetone and a methyl formate are separately supplied simultaneously to the methanol solution of sodium methoxide. The resultant mixture is sufficiently stirred over a predetermined period of time so as to carry out the reaction to form sodium formyl acetone. Also provided is a method of preparing 4,4-dimethoxy-2-butanone. In this method, the reaction mixture obtained in the reaction to form sodium formyl acetone is directly charged into a reaction vessel simultaneously with sulfuric acid to neutralize and acetalize sodium formyl acetone contained in the reaction mixture so as to obtain 4,4-dimethoxy-2-butanone. |
