Zusammenfassung: | The present invention relates to a method capable of utilizing DD mixture to prepare acrylate and separating 1,2-dichloropropane from it. Said invention utilizes the action of 1,3-dichloropropene in the DD mixture and acrylic acid or methylacrylic acid, alkali, catalyst and and polymerization inhibitor to synthesize 3-chloro-2-propenyl acrylate or 3-chloro-2-propenyl 2-methacrylate, and utilizes the distillation to make it be separated from 1,2-dichloropropane. Said method includes the steps of raw material pretreatment, catalytic esterification reaction, product separation and product refinement. |
