Petroleum — derived naphthalene is usually purer than that derived from coal tar. Approximately 1. Another source differentiates light and heavy comments on the hydrocarbon structure, but offers a less precise dividing line:. Light is a mixture consisting mainly of straight — chained and cyclic aliphatic hydrocarbons having from five to six carbon atoms per molecule.
Heavy is a mixture consisting mainly of straight — chained and cyclic aliphatic hydrocarbons having from seven to nine carbon atoms per molecule. Both of these are useful definitions, but they are incompatible with one another and the latter does not provide for mixes containing both six and seven carbon atoms per molecule.
These terms are also sufficiently broad that they are not widely useful. Naphtha is used mainly as a precursor to other chemicals. The single largest use is the industrial production of Phthalic Anhydried, although more Phthalic Anhydride is made from O — Xylene. Heavy crude oil dilution:.
Other common dilatants include natural gas condensate and light crude. However, naphtha is a particularly efficient dilutant and can be recycled from diluted heavy crude after transport and processing. The importance of oil dilutants has increased as global production of lighter crude oils has fallen and shifted to exploitation of heavier reserves.
Light naphtha is used as a fuel in some commercial applications. Naphtha is sometimes preferred over kerosene due to a lower incidence of fuel line clogging. Naphtha is a crucial component in the production of plastics. Wetting agent and Surfactant:. Alkyl Naphthalene Sulfonates ANS are used in many industrial applications as nondetergent wetting agents that effectively disperse colloidal systems in aqueous media.
The major commercial applications are in the agricultural chemical industry, which uses ANS for Wettable Powder and Wettable Granular Dry — Flowable formulations, and the textile and fabric industry, which utilizes the wetting and defoaming properties of ANS for bleaching and dyeing operations. It has been used as a household fumigant. Structure of naphthalene. Uses of Naphthalene. Naphthalene is a chemical used to make lubricant, insecticide, antiseptic, lubricant, dye, resin, solvents, plastics, in tanning leather applications, and many other commercial and consumer products.
Naphthalene is used to make products like moth balls that repel and keep moths away. All rights reserved. Class » Chemistry. Share with your friends. Priya G N answered this.
