Sodium naphthalene is an organic salt with the chemical formula Na + [C 10 H 8] −. In the research laboratory, it is used as a reductant in the synthesis of organic, organometallic, and inorganic chemistry. It is usually generated in situ. When isolated, it invariably crystallizes as a solvate with ligands bound to Na +. [1]
With alkali metals, naphthalene forms the dark blue-green radical anion salts such as sodium naphthalene, Na + C 10 H − 8. The naphthalene anions are strong reducing agents. Naphthalene can be hydrogenated under high pressure in the presence of metal catalysts to give 1,2,3,4-tetrahydronaphthalene(C 10 H 12), also known as tetralin.
Poly-Etch is a sodium naphthalene complex in tetraglyme, [3] while Fluoro-Etch is a sodium naphthalide complex in diglyme [4] Matheson, the manufacturer of Poly-Etch, also manufactures a monoglyme-based etchant called Poly-Etch W. [5] Fulcrum Chemicals manufactures three different etchants called Natrex25, NatrexHighFp and Natrex64.

Sodium atoms have 11 electrons, one more than the stable configuration of the noble gas neon. As a result, sodium usually forms ionic compounds involving the Na + cation. [1] Sodium is a reactive alkali metal and is much more stable in ionic compounds. It can also form intermetallic compounds and organosodium compounds.
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.
Aminonaphthalenesulfonic acids are compounds with the composition C 10 H 6 (NH 2)(SO 3 H), being derived from naphthalene (C 10 H 8) substituted by an amino and sulfonic acid groups. These compounds are colorless solids. They are useful precursors to dyes. [1]
Naphthalene is a major component of some mothballs.It repels moths as well as some animals. [citation needed]Since mothballs that contain naphthalene are considered hazards, safer alternatives have been developed, such as the use of 1,4-dichlorobenzene, however, 1,4-dichlorobenzene has been declared as a potential neurotoxin. 1,4-dichlorobenzene has been linked to potentially causing ...
