| Zusammenfassung: | The characteristic of this invention is that: using recovered low-boiler or acetic acid to humidize the sucked gas in separator in the sperating of chloracetic acid crystal and mother solution, reducing the content of dichloroacetic acid, then feeding smelt chloracetic acid to rectifying tower to remove left low-boiler or acetic acid, after distillation, condensation, the high purity chloracetic acid is obtained. Said invention not only has a chloracetic acid of more than 99.0% poureness and is suitable for producing in large scale but also. |
