Production capacity of benzotrichloride was estimated at 80,000 tonnes for the year 2000. It is produced by the free radical chlorination of toluene, catalysed by light or radical initiators such as dibenzoyl peroxide. Mono- and di-chlorinated intermediates are observed as benzyl chloride and benzal chloride: [2] C 6 H 5 CH 3 + Cl 2 → C 6 H 5 ...
Benzene is a natural constituent of petroleum and is one of the elementary petrochemicals. Due to the cyclic continuous pi bonds between the carbon atoms, benzene is classed as an aromatic hydrocarbon. Benzene is a colorless and highly flammable liquid with a sweet smell, and is partially responsible for the aroma of gasoline.
tert-Butylbenzene can be produced by the treatment of benzene with isobutene [1] or by the reaction of benzene with tert-butyl chloride in presence of anhydrous aluminium chloride, [2] the latter is depicted below:
Ethylbenzene is an organic compound with the formula C 6 H 5 CH 2 CH 3.It is a highly flammable, colorless liquid with an odor similar to that of gasoline.This monocyclic aromatic hydrocarbon is important in the petrochemical industry as a reaction intermediate in the production of styrene, the precursor to polystyrene, a common plastic material.
The traditional method using benzene became uneconomical due to the high and still rising benzene prices and by complying with the regulations of benzene emissions. In addition, in the production of maleic anhydride (4 C-atoms) a third of the original carbon atoms is lost as carbon dioxide when using benzene (6 carbon atoms).
In the next year, Fittig et al. adopted the pseudocumol terminology, [7] in 1869 Fittig and B. Wackenroder proved that the fraction is a mixture of mesitylene with another trimethylbenzene, for which the name of pseudocumol was retained, [8] and in 1886 Oscar Jacobsen showed that the third trimethylbenzene he discovered earlier is also present.

1,4-Bis(trichloromethyl)benzene is an organic compound with the formula C 6 H 4 (CCl 3) 2. A white solid, it is prepared industrially by chlorination of para-xylene. It reacts with terephthalic acid to give terephthaloyl chloride, a precursor to Kevlar. [1] It also reacts with sulfur dioxide to give the same acid chloride and thionyl chloride. [2]
