It is a viscous liquid mixture of hydrocarbon compounds and polishing on Steel and Aluminium components which are used for industrial purpose in many various industries, derived, along with coke, from the destructive distillation of coal in coking ovens. Being flammable, Coaltar is used for heating or to fire boilers for impregnating of graphite electrode & refractory bricks, for all binding application. Coal tar was discovered around 1665 and used for medical purposes as early as the 1800’s. It is on the World Health Organization’s List of Essential Medicines, the most effective and safe medicines needed in a health system.

Coaltar pitch is a thick black liquid that remains after the distillation of Coaltar. It contains many chemical compounds including carcinogens such as benzene. Studies of coke-oven pitch indicate that coal-tar pitch contains: four-membered aromatic hydrocarbon ring systems (e.g. chrysene, fluoranthene, pyrene, triphenylene, naphthacene and benzanthracene); five-membered ring systems; six-membered ring systems (dibenzopyrenes, dibenzofluoranthenes and benzoperylenes); and seven-ring systems (coronene). Other aromatic chemicals in coal-tar pitch include methylated and polymethylated derivatives, mono- and polyhydroxylated derivatives, and heterocyclic compounds.

Anthracene oil is a heavy green oil (partially solidifying on cooling), which distills over from coal tar at a temperature above 270°. It is used as feedstock to manufacture carbon black and coal tar enamel. Anthracene Oil is primarily used to make paints. These oils are carefully obtained through coal tar distillation process.
