2synthesis methods
- Product Name:sodium p-[(4,6-dichloro-1,3,5-triazin-2-yl)amino]benzenesulphonate
- CAS Number:4156-21-2
- Molecular formula:C9H7Cl2N4NaO3S
- Molecular Weight:345.13
Yield:-
Reaction Conditions:
with sodium hydroxide in water at 10; pH=6;
Steps:
9
A solution of 18.2 parts aniline-4-sulphonic acid and 4.2 parts sodium hydroxide in 20parts water is added to a stirred suspension of 19.4 parts cyanuric chloride in 60 partsice water. The pH is kept at 6 by the dropwise addition of 30% sodium hydroxide. Themixture is stirred below 10°C until primary aromatic amine groups can no longer bedetected by the diazo reaction.
