| titleOfInvention | A kind of continuous flow method for preparing 3,5-dichloro-2-pentanone |
| abstract | The invention relates to a continuous flow method for preparing 3,5-dichloro-2-pentanone. In a continuous flow reaction device, α-acetyl-α-chloro-γ-butyrolactone and hydrochloric acid are simultaneously mixed with a metering pump. It is pumped into the reaction device and continuously reacted at 50-90 °C to obtain 3,5-dichloro-2-pentanone. Compared with the traditional kettle type reaction method, the technical scheme of the invention avoids long-term contact between the product and the acid, the product has a short residence time, does not generate by-products and tar, and has the advantages of simple operation and post-processing, and high product yield and purity. advantage. |
