| titleOfInvention | Synthesis process of 3, 5-dichloro-2-pentanone |
| abstract | The invention discloses a synthesis process of 3, 5-dichloro-2-pentanone, which takes water as a solvent, and alpha-acetyl-gamma-butyrolactone is subjected to continuous reactions of sulfonyl chloride chlorination, hydrolytic ring opening, decarboxylation and re-chlorination in a double-layer glass reaction kettle to obtain high-purity 3, 5-dichloro-2-pentanone. Compared with the traditional process, the method has the advantages that the reaction can be completely carried out without adding any catalyst, the method is safe and environment-friendly, the cost is low, the reaction yield is high, the industrial operability is strong, and the method has a good application prospect. |
