Process for preparing substituted 4,4'-diaminostilbene-2,2'-disulphonic acid salts |
| abstract |
In the preparation of substituted 4,4'-diaminostilbene-2,2'-disulfonic acid salts a clear increase in the reaction rate may be achieved by carrying out the reaction of the tetrachlorine derivative (III) with the aniline (IV) in the presence of the amine (VI) as acid-absorber. |
