Sodium 1-naphthalenesulfonate Usage And Synthesis

Description

Sodium 1-naphthalenesulfonate (CAS Registry No. 130-14-3) is a valuable regent widely used in the functionalized reduced graphene oxide stabilization of silver nanoparticles. Meanwhile, this is an intermediate in manufacturing 8-Anilino-1-naphthalenesulfonate and 8-p-toluidino-1- naphthalenesulfonate, and many other applications. Sodium 1- and 2-naphthalenesulfonate are mainly synthesized by sulphonation naphthalene with concentrated sulfuric acid then condensation by NaCl. The products formed by this method included sodium 1- and 2-naphthalenesulfonates in various proportions. They were obtained through sulphonation and condensation, respectively. Purifying sodium 1- and 2-naphthalenesulfonates via crystallization in a solvent is very important[1-2].

Chemical Properties

Deliquescent crystals.Soluble in water, alcohol, and ether. Combustible.

Uses

Sodium 1-naphthalenesulfonate was employed as a detection reagent to investigate ion-pair high-performance liquid chromatographic retention behavior of copper(II)-1-oxa-4,7,10,13-tetraazacyclopentadecane complex. It was also employed as a stationary liquid phase for resolution of dichlorophenol isomers by GC.

Uses

Starting point in the manufacture of α-naphthol, α-naphthalene sulfonic acid, α- naphthylaminesulfonic acid; solvent (Na salt) for phenol in the manufacture of disinfectant soaps.

Flammability and Explosibility

Not classified

Purification Methods

Recrystallise it from water or aqueous acetone [Okadata et al. J Am Chem Soc 108 2863 1986]. [Beilstein 11 IV 521.]
