| titleOfInvention | Electrochemical process for preparing 4,4'-dinitrostilbene-2,2'-disulfonic acid and the salts thereof |
| abstract | A process is disclosed for electrochemically treating p-nitrotoluene-2-sulfonic acid salts under oxidizing conditions to form 4,4'-dinitrostilbene-2,2'-disulfonic acid or the salts thereof. The process provides satisfactory yields of the stilbene compound while enabling substantial recycling of reaction materials. Substantial benefits are obtained when lithium hydroxide is employed in the reaction medium, including recovery of product of high purity, and improved recovery and recycling of lithium to the process. |
