GENERAL DESCRIPTION |
||
|
Benzene (C6H6), also called benzol (coal naphtha), is an aromatic flammable hydrocarbon liquid produced by coking coal in steel industries and is synthesised from natural gas. Benzene is a chemical that occurs naturally in crude oil. Natural benzene is supplemented by additional volume made in the refining process. Benzene is used in making many common products such as tires, carpets, compact discs and pharmaceuticals. |
