Industrial Chemical

• Multi-sectorial uses
• Effective
• Longer shelf life

• Surfactant – May be used in the agricultural, textile or fabric industries
• Fumigant that may be used in pesticides (such as mothballs)
• Special Effects and Pyrotechnics – Naphthalene produces a large explosion of black smoke that may be used for movies or military training
• Naphthalene is a chemical compound with formula C₁₀ H_8. The two kinds of naphthalene concentrates that may be obtained from coal tar are known as crude and refined naphthalene

• Phthalic anhydride
• Concrete superplasticizers
• Tanning agents and dyestuffs
• B-naftol
• Tetralin and Decalin
• Mothballs and other compacted products for household use
• It is also a raw material to obtain a large number of intermediate organic compounds used in fine chemical and pharmaceutical processes
• Naphthalene that is produced during coal tar distillation is called crude naphthalene. When it is further processed, in different stages, we get Refined Naphthalene of minimum 98 % purity. It is a white or light yellow, flaky or powdery crystal. It is easily volatile and has a special aromatic smell. It is highly sublime and does not dissolve in water but can dissolve in benzene, alcohol, ethers, chloroform, carbon disulfide etc
• Naphthalene is used in manufacturing of SNF, beta napthol, phthalicanhydride, tanning agents, moth balls, and domestic disinfectants. It is used in dyes, chemicals and pharmaceutical industries
• It is used in pyrotechnic special effects such as the generation of black smoke and simulated explosions. In the past, naphthalene was administered orally to kill parasitic worms in livestock. Naphthalene and its alkyl homologs are the major constituents of creosote
• Naphthalene is used in engineering to study heat transfer using mass sublimation

1,2-Dichlorobenzene, or orthodichlorobenzene (ODCB), is an organic compound with the formula C₆H₄Cl₂. This colourless liquid is poorly soluble in water but miscible with most organic solvents. It is a derivative of benzene, consisting of two adjacent chlorine centers.

It is mainly used as a precursor chemical in the synthesis of agrochemicals, as a preferred solvent for dissolving and working with fullerenes, as an insecticide, and in softening and removing carbon-based contamination on metal surfaces.

1,2-Dichlorobenzene is obtained as a side-product of the production of chlorobenzene:

The reaction also affords the 1,4- and small amounts of the 1,3-isomer. The 1,4- isomer is preferred over the 1,2- isomer due to steric hindrance. The 1,3- isomer is uncommon because it is a meta- compound, while chlorine, like all halogens, is a ortho/para- directors in terms of electrophilic aromatic substitution.

It is mainly used as a precursor to 1,2-dichloro-4-nitrobenzene, an intermediate in the synthesis of agrochemicals. In terms of niche applications, 1,2-dichlorobenzene is a versatile, high-boiling solvent. It is a preferred solvent for dissolving and working with fullerenes. It is an insecticide for termites and locust borers, historically used by the United States Forest Service to combat widespread bark beetle outbreaks.

1,2-Dichlorobenzene is also used in softening and removing carbon-based contamination on metal surfaces
