| 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].
