• Production via Sulfonation and Neutralisation: The feedstock for this process includes alpha naphthylamine (C10H9N), sulfuric acid (H2SO4), o-dichlorobenzene (C6H4Cl2), and sodium carbonate (Na2CO3). The manufacturing process of sodium naphthionate involves a sulfonation reaction followed by neutralisation. First, alpha naphthylamine is sulfonated with concentrated sulfuric acid. The reaction takes place in the presence of o-dichlorobenzene (ODCB), which acts as a high-boiling solvent, helping to control the exothermic reaction. The mixture is heated to a higher temperature (around 130−160 degree Celsius) for a specific duration, leading to the formation of naphthionic acid (1-naphthylamine-4-sulfonic acid) as the primary product. After the sulfonation is complete, the mixture is cooled, and then carefully neutralised with sodium carbonate solution to form sodium naphthionate as the final product.
