PROCEDE DE TRAITEMENT DE SOLUTIONS AQUEUSES COMPRENANT DES ACIDES ET DES COMPOSES NITRES |
摘要 |
<p>The invention concerns a method for treating an aqueous solution derived from sluicing of crude mononitrated or dinitrated aromatic compounds obtained by nitration of the corresponding aromatic compounds, consisting in: (a) contacting said aqueous solution with said aromatic compound thereby obtaining an aqueous phase and an organic phase; (b) recycling said organic phase in the nitration process; (c) distilling said aqueous phase; (d) recycling the resulting concentrated acid solution in the nitration process; (e) recycling or eliminating the recuperated water after distillation.</p> |
