REACTIONS OF OXALACETIC ACID AND THE FERRIC AND AMMONIUM COMPLEXES OF OXALACETIC ACID,
Abstract
Reactions of oxalacetic acid were investigated in acidic, neutral, and alkaline solutions. In addition to its well-known decarboxylation reaction, oxalacetic acid can be transformed by heating in 0.1 M HClO4 into a compound with an absorption peak at 230 millimicrons. This compound reacts with ferric iron, as oxalacetic acid also does. Ferric oxalacetate chelates can be formed in both acidic and alkaline solutions. At pH 1-4 ferric oxalacetic acid rapidly decomposes. In alkaline solutions it appears relatively stable. In contrast, the ammonium oxalacetate complex, which absorbs at 285 millimicrons, decomposes rapidly in neutral and mildly alkaline solutions. Above pH 9.5 the ammonia oxalacetate complex is relatively stable. (Author)
