| titleOfInvention |
Method for extracting nitrocresols from waste water produced in the manufacture of mononitrotoluene and use of said extract |
| abstract |
The invention provides a process for removing nitrocresols from wastewater of mononitrotoluene preparation, which comprises acidifying the alkaline wastewater of mononitrotoluene preparation with acids to a pH of at most 3 and treating the nitrocresols with an extractant. n The invention further provides the preparation of dinitrotoluene by use of the nitrocresol-containing extracts as a feedstock. |
