| titleOfInvention | Recovery treatment method of 4,4' -diaminodiphenyl ether sublimation residue |
| abstract | The invention relates to the technical field of recovery of fine chemical organic materials, in particular to a recovery treatment method of 4,4' -diaminodiphenyl ether sublimation residues. According to the method for recycling the 4,4 '-diaminodiphenyl ether sublimation residue, 4' -diaminodiphenyl ether in the 4,4 '-diaminodiphenyl ether sublimation residue which is directly treated as hazardous waste originally is recycled, the recovery rate is up to 95.625%, the purity of the recycled 4,4' -diaminodiphenyl ether is up to 99.78%, resources are saved, resource recycling is realized, and the treatment cost of the hazardous waste is effectively reduced. |
