| titleOfInvention | Desalination Method of Aqueous Sulfonamide Solution |
| abstract | To remove salts (particularly NH 4 Cl) present in aqueous sulfonamide solutions (particularly CH 3 SO 2 NH 2 ), the solution must be treated by a two-part electrodialysis method.n n n The pH can be maintained at 7 or below to suppress the formation of ammonia. After crystallization, the demineralized solution can be concentrated to recover the sulfonamide. |
