Process for the preparation of 4,4'-dinitrostilben-2-2'-disulfonic acid |
| abstract |
The novel process for the preparation of 4,4'-dinitrostilbene-2,2'-disulphonic acid and their salts by oxidising 4-nitrotoluene-2-sulphonic acid with an oxidant in the presence of strong bases is characterised in that the oxidation is carried out in at least one polyamine as the solvent. |
