| titleOfInvention | Rectification method for 3,5-dichloro-4-aminotrifluorotoluene as well as light tower system and rectification tower system applied in rectification method of 3,5-dichloro-4-aminotrifluorotoluene |
| abstract | The invention discloses a rectification method for 3,5-dichloro-4-aminotrifluorotoluene as well as a light tower system and a rectification tower system applied in the rectification method of the 3,5-dichloro-4-aminotrifluorotoluene. The rectification method of 3,5-dichloro-4-aminotrifluorotoluene comprises the following steps of: checking each equipment, performing a pressure test on a system, adding materials, opening a light tower steam inlet valve and a light tower trap bypass valve to thoroughly drain condensed water, opening a light tower trap stop valve, closing the light tower trap bypass valve, performing reflux, opening a pre-distillation extraction valve, extracting a product to a pre-distillation kettle, charging in a rectification tower, performing reflux, sampling, and extracting a finished product for a finished product receiving tank, wherein the light tower system comprises the light tower, the pre-distillation kettle and a light tower distillation kettle; the rectification tower system comprises the rectification tower, a rectification tower distillation kettle and the finished product receiving tank. The rectification method, the light tower system and the rectification tower system disclosed by the invention have the following beneficial effects that raw materials are saved, final yield is increased, the quantity of kettle residues is greatly reduced, and considerable economic benefits are obtained; meanwhile, dangerous solid waste treatment and transfer amount are reduced, and good environmental benefits are obtained. |
