8‐Quinolinols which are substituted in the aromatic nucleus by nitro‐, chloro‐, or by sulfonic acid groups underwent a neat thermal fragmentation upon heating in 75% nitric acid as reaction medium yielding 2,3‐dicarboxypyridinium nitrate. The scope and the mechanism of these reactions are discussed.
