Method for continuously preparing epsilon-lactone |
| abstract |
The invention discloses a method for continuously preparing epsilon-lactone. The method for continuously preparing the epsilon-lactone comprises the following steps: in the presence of boric acid, continuously oxidizing a carboxylic acid solution by adopting hydrogen peroxide in multiple stirring reaction kettles provided with a rectifying tower, continuously introducing the obtained percarboxylic acid and cyclohexanone into the multiple stirring kettles which are connected in series, carrying out a reaction to obtain an epsilon-lactone solution, and carrying out continuous rectification, thus high-purity epsilon-lactone is obtained. |
