Systematic and Applied Microbiology. Because chlorine is electronegative, C 6 H 5 Cl exhibits culorobenzene decreased susceptibility to further chlorination. This page was last edited xhlorobenzene 15 Novemberat 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: Journal of Geophysical Research: It was first described in The conversions of the 4-nitro derivative are similar.
The major use of chlorobenzene is as an intermediate in the production of commodities such as herbicides, dyestuffs, and rubber. Mads, because it has only been found at 97 out of 1, NPL hazardous waste sites, it is not considered a widespread environmental contaminant. Chlorobenzene is an aromatic organic compound with the chemical formula C 6 H 5 Cl. At one time, chlorobenzene was the main precursor ,sds the manufacture of phenol: Chlorobenzene can be produced by from aniline via benzenediazonium chloridethe route being known as the Sandmeyer reaction.
Chlorobenzene exhibits “low mss moderate” toxicity as indicated by its LD 50 of 2. From Wikipedia, the free encyclopedia. Chlorobenzene can persist in soil for several months, in air for about 3. LC Lo lowest published.

Upon entering the body, typically via contaminated air, chlorobenzene is excreted both via the lungs and the urinary system. 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.
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 methoxidesodium disulfide, and ammonia.
Views Read Edit View history. Chlorobenzene is also used as a high-boiling solvent in many industrial applications as well as in the laboratory. This colorless, flammable liquid is a common solvent chlorkbenzene a widely used intermediate in the manufacture of other chemicals.
The heating would have triggered a reaction of organics in the Martian soil, which is known to contain perchlorate. The bacterium Rhodococcus phenolicus degrades chlorobenzene as sole carbon sources.
Chlorobenzene – Wikipedia
Humans may be exposed to this agent via breathing contaminated air primarily via occupational exposureconsuming chloobenzene food or water, or by coming chkorobenzene contact with contaminated soil typically near hazardous waste sites. Industrially the reaction is conducted as a continuous process to minimize the formation of dichlorobenzenes. Inthe SAM science team announced that the Curiosity rover reported evidence of higher concentrations of chlorobenzene in a sedimentary rock, named ” Cumberland “, on Mars.
