derivatives of naphthalene of the general formula C10H8-n (NO2)n, where n = 1,2, 3, or 4. Alpha-nitronaphthalene and the 1,5- and 1,8-dinitronaphthalenes are of commercial significance. They are light-yellow crystalline compounds (melting points, 57.8°C, 219°C, and 172°C, respectively). Alpha-nitronaphthalene is readily soluble in most organic solvents; both of the dinitronaphthalenes are poorly soluble.
Nitronaphthalenes are produced by nitration of naphthalene by a nitrating mixture; a mixture of 1,5- and 1,8-dinitronaphthalenes is also produced upon nitration of α-nitronaphthalene. Nitronaphthalenes are used in the production of sulfur dyes and azo dyes.
