## Abstract The isomerisation of 2‐naphthol‐1‐sulfonic acid (potassium salt) into 2‐naphthol‐6‐sulfonic acid has been studied using labelled sulfuric acid (H~2~^35^SO~4~). In 40 to 50% aqueous sulfric acid the reaction takes place exclusively by an intermolecular mechanism (protio‐desulfonation and
