n: liquid chemical derived from benzene or from benzene and ammonia. It is used as a solvent and in the organic synthesis of other substances.

n: C6H7N, colourless and oil like liquid, tang and toxic. Usually used in measuring content of aromatic hydrocarbon in drilling fluid operation.

describing members of a family of chemicals with a ring structure of carbon chains. Normally xylene, toluene, etc. Benzene is a aromatic but is not used.

n pi: hydrocarbons derived from or containing a benzene ring. Many have an odour. Singlering aromatic hydrocarbons are the benzene series (benzene, ethylbenzenes, and toluene). Aromatic hydrocarbons also include naphthalene and anthracene. Compare aliphatic hydrocarbons.

n: C6H6 colourless, volatile, flammable toxic liquid aromatic hydrocarbon used as a solvent and as a motor fuel.

an aromatic (cyclic or ring structure) compound, present in very minor quantities in many crude oils.

n: the structural arrangement of atoms believed to exist in benzene.

benzene, toluene, xylene.

n: C6H5OH, a white, crystalline, water-soluble, poisonous mass obtained from coal tar, or a hydroxyl derivative of benzene.

n: (PCB) a family of highly toxic chemical cornpounds consisting of two benzene rings in which chlorine takes the place of two or rnore hydrogen at- orns;known to cause skin diseases and sus- pected of causing birth defects and cancer.

n: any of three flammable hydrocarbons, C6H4(CH3h, similar to benzene. A commercial mixture is used as a solvent when oilfield emulsions are being tested.
