Naphthalenesulfonates are derivatives of sulfonic acid which contain a naphthalene functional unit. A related family of compounds are the aminonaphthalenesulfonic acids. Of commercial importance are the alkylnaphthalene sulfonates, which are used as superplasticizers in concrete. They are produced on a large scale by condensation of naphthalenesulfonate or alkylnaphthalenesulfonates with formaldehyde.[1][1]
