chlorobenzene

[‚klȯr·ō′ben‚zēn]
(organic chemistry)
C6H5Cl A colorless, mobile, volatile liquid with an almondlike odor; used to produce phenol, DDT, and aniline.

Chlorobenzene

 

a colorless liquid, with a characteristic odor and a boiling point of 131.7°C. Chlorobenzene is practically insoluble in water but is soluble in many organic solvents.

In industry chlorobenzene is produced by the catalytic chlorination of benzene, carried out at 75°–85°C using metallic iron as the catalyst. It is used in the production of phenol, 4,4′-dichlorodiphenyltrichloroethane (DDT), and intermediate products during the synthesis of dyes. It is also used as a solvent in laboratory work.

As the researchers involved in the study suggest it is also possible chlorobenzene detected decades ago might be that trapped from Earth and contaminated the lander's equipment.
According to Melissa Guzman, a scientist at LATMOS research centre, while the findings are interesting, the chlorobenzene may have come from material carried on the probe from Earth.
We have expanded the scope of work on air toxics and ASD to consider measures of the autism phenotype in order to explore how risks for disease may differ from those for severity, finding that autism severity may be influenced by carbon disulfide and chlorobenzene. The novel use of a multiplex sample and associated statistical approach to control confounding may account for differences in results from prior studies and may limit generalizability.
The copolymer was soluble in several organic solvents, such as chloroform, 1,2-dichlorobenzene, chlorobenzene, THF, and xylene.
Note that chlorobenzene was found to be not an appropriate solvent for spin-coating deposition of the polymer on the PDMS surface due to dewetting issues, and the complete deposition of P3HT could be achieved only using chloroform at an appropriate spin speed (~1000 rpm).

Compound (23) 1,2-bis(benzimidazolyl)-4- chlorobenzene: Yield: 70%; Anal.
Firstly, 1 mL aliquots of the 5 [micro]g/mL working solution were pipetted into a 2-mL sample vial with a screw-cap to which a 25 [micro]L mixture of 1: 4 chlorobenzene : ethyl acetate was then pipetted; 15 mg NaCl was weighted and then added to the solution.
Heptachlor epoxide was correlated with cis-chlordane, and several chlorobenzene related compounds (1,2,3,4-TeCBz, PeCBz, and PCA) had weak but nonsignificant (P = 0.05-06) relationships with 1,2,4,5-TeCBz and [alpha]-HCH; oxychlordane was not correlated with any other OCPs (Table S9B).
Chlorobenzene dissolved in an organic solvent is an important raw material and intermediate in the pharmaceutical, leather, dye and other industries, where it is widely used.
