| titleOfInvention | Production method of high-purity dichlorodiphenylene ether ketone |
| abstract | The invention relates to the technical field of intermediate synthesis, in particular to a production method of high-purity dichlorodiphenylene ether ketone, aiming at improving the product yield, reducing the production cost and reducing the discharge amount of waste liquid. Which comprises the following steps: s1: dissolving dichlorodiphenyl ether in chloropropane, adding the solution into an open carbon steel reaction kettle, stirring, and controlling the temperature in the carbon steel reaction kettle to be stable; s2: adding a sulfuric acid catalyst into the reaction kettle, cooling, and then dropwise adding acetyl chloride into the reaction kettle; s3: after the dropwise addition is finished, preserving heat for 2-2.5h, finishing the reaction, gradually cooling the reaction kettle, and discharging the feed liquid to a hydrolysis kettle for hydrolysis; s4: hydrolyzing, desolventizing, decolorizing, crystallizing, centrifuging and air drying the feed liquid to obtain a finished product. |
