Process for extracting and disposing of nitrophenolic by-products |
| abstract |
A process for treating nitrophenolic by-products contained in nitration waste water including the steps of solvent extraction, solvent and nitrophenolic residue recovery by distillation, and incineration of the nitrophenolic residue is disclosed. The extraction process involves the extraction of the nitrophenolic by-products from the nitration waste water utilizing a solvent in the presence of an acid at an elevated temperature and acidic pH. The extraction produces a nitrophenolic solvent solution which is subjected to a distillation to recover the solvent for reuse and produce a residue containing the nitrophenolic materials. The residue can be disposed of by incineration. |
