   Coal Tar Pitch

Coal tar is a brown or black liquid of high viscosity, which smells of Naphthalene and aromatic hydrocarbons. Coal tar is among
the by-products when coal is carbonized to make coke or gasified to make coal gas. Coal tars are complex and variable mixtures
of phenols, polycyclic aromatic hydrocarbons (PAHs), and heterocyclic compounds, about 200 substances in all.Coal-tar pitches are used primarily as the binder for aluminum-smelting electrodes (IARC 1984). They are also used in roofing materials, to impregnate and strengthen refractory brick (for lining industrial furnaces), and in surface coatings, such as pipe-coating enamels and black varnishes used as protective coatings for industrial steelwork and as antifouling paints for boats.


   Carbon Black Feedstock

Carbon Black Feedstock is a mixture of C12 and higher components rich in Naphthalene, methyl-indenes, anthracene, fluorene and other poly-aromatic components. It originates from the high temperature cracking of petroleum fractions. Carbon Black Feedstock is used to produce Carbon Black, which is used for reinforcements, black pigments (e.g. for road markings) or conductors. The stream also contains piperylene, which is used to produce copolymerization elastomers, petroleum resins, curing agents, pesticides and perfumes.


   Middle Coal Tar Oil (Naphthalene Fraction)

Naphthalene fraction consists of 80-85% naphthalene (as far as methylnaphthalenes, thionaphthenes, phenols, non-saturated
combinations, indole, etc). Naphthalene fraction is used for the manufacture of phthalic anhydride and masticators.

   Creosote

Creosote is the portion of chemical products obtained by the distillation of a tar that remains heavier than water, notably useful for its anti-septic and preservative properties. It is produced in some quantities from the burning of wood and coal in blast furnaces.
creosote is to some extent used for wood preservation, but generally mixed with coal-tar creosote, since it isn't as effective. Commercially available preparations of "liquid smoke", marketed to add a smoked flavor to meat and aid as a preservative, consist primarily of creosote and other constituents of smoke. Creosote is the element which gives liquid smoke its function; guaicol lends to the taste and the creosote oils help act as the preservative.

   Carbolic Oil

Alkaline sodium phenolate produced by removing phenol in carbolic oil fraction and waste water and alkaline sodium phenolate produced by extracting phenol from naphthalene oil are processed by washing, steam blowing, and decomposing to get crude phenol. Crude phenol is white or colorless deliquescent crystal, nubbly, with notable sharp burning smell and taste, is soluble in water, can dissolve in alcohol, can be used in the production of synthetic fiber, pesticide, engineering plastics, dyes intermediates. Mainly extracting phenol, o-cresol, meta para cresol, xylenol, 35 - xylenol, is the solvent of senior insulating paint, and also is the important raw material for the industries such as plastics, pharmaceuticals, mildewproof agent etc.. 

 
   Phenol

Phenol, also known as Carbolic acid and Phenic acid, is an organic compound. It is a white chrystalline solid at room temperature.
The molecule consists of a phenyl group bonded to a hydroxyl group it is mildly acidic, but requires careful handling due to its propensity to cause burns. Phen was first extracted from Coal tar, but today it is produced on a large scale (about 7 billion kg/year)
using industrial processes. It is an important industrial commodity as a precursor to many materials and useful compounds. It's
major use involves its conversion to plastic related materials. Phenol and its chemical derivatives are key for building polycarbonates, epoxies, bakelite, nylon, detergents and a large collection of drugs and herbicides.

   Acetone

Acetone is the organic compound with the formula (CH3)2CO. This colorless, mobile, flammable liquid is the simplest example of the ketones. Acetone is miscible with water and serves as an important solvent in its own right, typically as the solvent
of choice for cleaning purposes in the laboratory. Familiar household uses of acetone are as the active ingredient in nail polish remover and as paint thinner. It is a common building block in organic chemistry.
