O-Toluene Sulfonamide (OTSA)
O-Toluenesulfonamide is a methylated sulfonamide and a major impurity if Saccharin. Studies suggest that o-Toluenesulfonamide has potential mutagenic activity.
Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
Chemical properties:
Colorless and flammable crystal, octahedral crystal in ethanol and prismatic crystal in water. Slightly soluble in water and ether, soluble in ethanol.
Production method
Reacting o-toluenesulfonyl chloride with ammonia and 60 ℃ for 2h, ammoniating to produce o-toluenesulfonamide. The reactant is cooled and filtered to obtain the crude product, which is then decolorized by activated carbon and refined by acid and alkali.
Precautions for operation:
No open flames.
