THERMOGRAVIMETRIC STUDY OF THE THERMAL-DE COMPOSITION OF AMIDOSULFONATES OF UNIVALENT METALS

The thermal decomposition of molten CsSO3NH2, NH4SO3NH2, RbSO3NH2, TIS O3NH2, NaSO3NH2 and KSO3NH2 was studied by means of thermogravimetry. A different behaviour of decomposition of the K and Na salts on the on e hand, and the other salts on the other, was found. While the decompo sition of CsSO3NH2, NH4SO3NH2, RbSO3NH2 and TISO3NH2 starts immediatel y on reaching the experimental temperature, the decomposition of the N a and K amidosulfonates starts after an incubation time. The activatio n energies of thermal decomposition of the salts studied were determin ed. (C) 1997 Elsevier Science B.V.
