| titleOfInvention | Caprolactam purification method |
| abstract | The present invention comprises a high-boiling substance, caprolactam, and optionally a low-boiling substance, and a) reacting 6-aminocapronitrile with water to obtain a reaction mixture, and b) the above reaction mixture Removing high-boiling substances from the crude caprolactam obtained by removing ammonia and unreacted water from the crude caprolactam, and c) supplying the crude caprolactam to the distillation column and The bottom temperature is set so as not to drop below 170 ° C., the first tributary as a product is obtained from the top, the second tributary is obtained from the bottom, and the caprolactam content of the second tributary is the first. And adjusting the second tributary to be 10% by mass or more based on the total of the two tributaries. |
