Manufacturing Process

This report comprises a thorough value chain evaluation for Sodium 2-Naphthalenesulfonate manufacturing and consists of an in-depth production cost analysis revolving around industrial Sodium 2-Naphthalenesulfonate manufacturing.

• Production from Naphthalene: The feedstock for this process includes naphthalene (C10H8), sulfuric acid (H2SO4), and sodium hydroxide (NaOH). The production of Sodium 2-naphthalenesulfonate starts with the reaction of naphthalene, which is a simple aromatic compound, with sulfuric acid. The reaction creates naphthalenesulfonic acid as an intermediate product. Further, the obtained intermediate is treated with sodium hydroxide, which causes a chemical change, turning it into Sodium 2-naphthalenesulfonate. The resulting solution of sodium 2-naphthalenesulfonate is then cooled to facilitate crystallisation. The solid product is then separated (e.g., by filtration or centrifugation) from the mother liquor, followed by drying to obtain Sodium 2-naphthalenesulfonate as the final product. The process involves two main steps, which include making the sulfonic acid from naphthalene and sulfuric acid and then neutralising that acid with sodium hydroxide to get the final product.
