Method for purifying wastewater from reprocessing of crude aromatic nitro compounds |
| abstract |
The invention relates to a method for purifying crude aromatic nitro compounds produced by the nitration of aromatic compounds, said method comprising performing the following washing stage (a) one or more times: (a) bringing the crude aromatic nitro compound (N-ein) into contact with an aqueous phase (W-res) and subsequent phase separation, maintaining an organic phase (N-res) and an aqueous phase (W-res), at least one demulgator (D) being present in one or more of the washing stages (a). |
