| Subject: How much do you know about Benzene? Fri Jul 15, 2011 8:41 am | |
| Benzene, also kanow as (6)Annulene, is clear colorless, highly flammable liquid with a petroleum-like odor. It evaporates into the air very quickly. Benzene is a natural constituent of crude oil, and is one of the most basic petrochemicals. It is widely used as solvent and precursor in a range of products. By substitution, addition reaction and benzene ring rupture reaction, many important chemical intermediates can be derived. Benzene is insoluble in water. In addition to glycerol, ethylene glycol, diethylene glycol, 1,4 - butanediol and other polyols, Benzene can be miscible with alcohol, chloroform, ether, carbon tetrachloride, carbon disulfide, glacial acetic acid, acetone, toluene, xylene, aliphatic hydrocarbon and most organic solvents. With the exception of slightly dissolved iodine and sulfur, the inorganic substance is insoluble in benzene. Benzene(cas no: 71-43-2) is toxic by inhalation, in contact with skin and if swallowed. Moreover, it is harmful that may cause lung damage if swallowed. In addition, Benzene has danger of very serious irreversible effects and serious damage to health by prolonged exposure that may cause heritable genetic damage. If you want to contact this product, you must wear suitable protective clothing and gloves. In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.) Please avoid exposure - obtain special instructions before use. | |
