Abstract
The thermal decomposition of oxalates of ammonium and potassium was studied by simultaneous TGA, DTA, and EGA (effluent gas analysis). Of the simple oxalates, the potassium compound is more stable than the lithium compound, as has been observed for the corresponding carbonates and sulfates. Ammonium oxalate is much less stable than either of the alkali metal oxalates. Potassium titanyl oxalate is less stable than potassium oxalate, and ammonium titanyl oxalate is more stable than ammonium oxalate.Keywords
