APPLICATIONS |
||
The prefix nitro- indicates the presence of NO2- radical, while nitrate refers
to any salt or ester of nitric acid or the NO3- anion. Nitroso- is the prefix
indicating presence of the group -NO and azo- is for -N=N- group. Some range of
organic compounds containing nitrogen include nitro compounds (RNO2 ), nitroso
compounds (RNO), amines (R3N ), amino acids, and natural alkaloids or
nucleotides. The nitrogen ion in nitro compounds is trigonally planar with 120°
angles. There are two resonance bonds so that the two oxygens are equivalent.
Nitro compounds are strongly basic due to electron withdrawing both inductively
and mesomerically. Historically, they
are abundant in dyes and explosives. Nitro compounds, organic hydrocarbons having one or more NO2
groups bonded via nitrogen to the carbon framework, are versatile intermediate
in organic synthesis.
1,8-Dinitronaphthalene is an intermediate for colorants (especially for sulfur colors) and other organic synthesis. |

| GENERAL DESCRIPTION OF NAPHTHALENE | ||
| Naphthalene is a white, volatile aromatic hydrocarbon with characteristic odor; insoluble in water, somewhat soluble in methanol/ethanol, soluble in organic solvents and very soluble in ether, chloroform, or carbon disulfide. Commercially it is available in molten form or in flaked form. It has the molecular structure of two fused or condensed benzene rings sharing two adjacent carbon atoms; C10H8. Naphthalene is obtained from coal tar which is distilled in the temperature range of 170 - 230 C and is treated with a sodium hydroxide solution to remove phenols. Naphthalene is obtained by the isolation from pyrolysis residue oils, olefin fractions, and petroleum-derived fractions. The distribution capacity is supposed to be about 60% coal-tar and 40% petroleum-derived naphthalene in U.S.A. It is an important parent material to produce numerous substitution products used in the manufacture of dyes, insecticides, organic solvents and synthetic resins. Phthalic anhydride is prepared by oxidizing naphthalene to be used in the manufacture of dyes, resins, plasticizers, and insecticides. Naphthalene sulfonate surfactants and dispersants, however, have increased their market share significantly and are expected to drive whatever growth there is for naphthalene. Naphthalene is the major raw material for Carbaryl, used as a general-purpose insecticide. Naphthalene is also used for moth repellents, fungicides, lubricants, explosives, wood preservatives, vermicides and hydronaphthalenes (tetralin, decalin). Hydronaphthalenes are used for major raw material for dyes, resins, plasticizers, and insecticides. They are also used in reactive and process solvents, heat transfer fluid, dye carrier, fuel additives, lubricants, ore flotation and oilfield chemicals. | ||
