| titleOfInvention | Method for treating cyproterone acetate ketal mother liquor |
| abstract | The invention discloses a method for treating a cyproterone acetate ketal mother liquor, which realizes the recycling of main components in the cyproterone acetate ketal oily mother liquor through the steps of acidification, decoloration and refining, reduces the environmental pollution, and ensures that the purity of the cyproterone acetate dehydrogenated product obtained by recycling is more than or equal to 98 percent; the dehydrogenated substance can be subjected to subsequent reaction through secondary ketal, so that the utilization rate of the material is improved; the pollution of hormone waste to the environment is reduced. |
