| titleOfInvention | Improved optical brightening agent for detergent formulations and a process for preparing the same |
| abstract | The present invention relates to a process for preparing disodium 4,4'-bis(4-anilino-6-morpholino-s- triazin-2-ylamino)-2,2'-stilbene disulphonate in the β crystal form, the process comprising subjecting disodium 4,4'-bis (4:anilino-6-morpholino-s-triazin-2-ylamino)-2,2'-stilbene disulphonate in the a crystal form to steam distillation. It also discloses a process to get formulations based on disodium 4,4'-bis(4- anilino-6-morpholino-s-triazin-2-ylamino)-2,2'-stilbene disulphonate, with substantially lower content of the hazardous amines such as aniline and morpholine. |
