Abstract
The decomposition pressure of the hydrate of sodium N-chlorobenzenesulfonamide has been measured from 25° to 77°. Thermal analysis show that the compound undergoes two transitions accompanied by a mass loss each time. The first transition occurs at 80° to 125° and is endothermic, whereas the second one, at 188°, is exothermic. The thermal decomposition of the chloramine salt leads to the formation of sodium chloride, benzenesulfonamide, chlorobenzenesulfonamide, diphenyl sulfone, nitrogen and sulfur dioxide.
