Journal of Geophysical Chlorobenzeene However, because it has only been found at 97 out of 1, NPL hazardous waste sites, it is not considered a widespread environmental contaminant.
At one time, chlorobenzene was the main precursor for the manufacture of phenol: Halogenated solvents Hazardous air pollutants Chlorobenene Aromatic solvents Phenyl compounds.
Chlorobenzene can be produced by from aniline via benzenediazonium chloridethe route being known as the Sandmeyer reaction. Lethal dose or concentration LDLC:.
These mononitrochlorobenzenes are converted to related 2-nitrophenol2-nitroanisole, bis 2-nitrophenyl disulfide, and 2-nitroaniline by nucleophilic displacement of the chloride, with respectively sodium hydroxidesodium chlorobnzenesodium disulfide, and ammonia. Chlorobenzene once was used in the manufacture of certain pesticidesmost notably DDTby reaction with chloral trichloroacetaldehydebut this application has declined with the diminished use of DDT.
The bacterium Rhodococcus phenolicus degrades chlorobenzene as sole carbon sources. Chlorobenzene exhibits “low to moderate” toxicity as indicated by its LD 50 of 2.
In other projects Wikimedia Commons. The conversions of the 4-nitro derivative are similar. Humans may be exposed to this agent via breathing contaminated air primarily via occupational exposureconsuming contaminated food or water, or by coming into contact with contaminated soil typically near hazardous waste sites. Retrieved from ” https: Chlorobenzene is also used as a high-boiling solvent in many industrial applications as well as in the laboratory. Upon entering the body, typically via contaminated air, chlorobenzene is excreted both via the lungs and the urinary system.
Chlorobenzene is an aromatic organic compound with the chemical formula C 6 H 5 Cl. Industrially the reaction is conducted as a vhlorobenzene process to minimize the formation of dichlorobenzenes.
This colorless, flammable liquid is a common solvent and a widely used intermediate in the manufacture of other chemicals. Systematic and Applied Microbiology. LC Lo lowest published.
Chlorobenzene – Wikipedia
Views Read Edit View history. Chlorobenzene can persist in soil for several months, in air for about 3.
Inthe SAM science team announced that the Curiosity rover reported evidence of higher concentrations of chlorobenzene in a sedimentary rock, named ” Cumberland “, on Mars. Ullmann’s Encyclopedia of Industrial Chemistry. It was first described in LD 50 median dose.
The catalyst enhances the electrophilicity of the chlorine. The major use of chlorobenzene is as an intermediate in the production of commodities such as herbicides, dyestuffs, and rubber. The heating would have triggered a reaction of organics in the Martian soil, which is known to contain perchlorate. Because chlorine is electronegative, C 6 H 5 Cl exhibits somewhat decreased susceptibility to further chlorination.
Chlorobenzene is manufactured by chlorination of benzene in the presence of a catalytic amount of Lewis acid such as ferric chloridesulfur dichlorideand anhydrous aluminium chloride:
