摘要
Three phenylenediammonium sulfate (PDAS) salts were prepared under solvent free conditions and characterized by gravimetric, spectroscopic and elemental analyses. Thermal decomposition studies of the salts have been investigated using TG (static air), TG/DTG and DSC (inert atmosphere). The thermal decomposition pathways have also been suggested and it has been found that PDAS salts on heating under vacuum in solid state give diaminobenzene sulfonic acids (DABSA) via proton transfer.
